This lets us *natively* handle varying physical sector sizes
without playing games and lying about the logical sector size.
(The original drives use 4K _physical_ sectors with 512B logical
sectors, but you have to access everything in 4K blocks...)
Achieve this by splitting the MAX_PHYS_SECTOR_SIZE code out
of the main ATA driver and re-using it.

Fuze+, native Sonys, and some of the Zens use 2K sectoring from
the partition/filesystem perspective, even though the underlying
storage used 512-byte sectoring.

This allows a single build to support ATA drives with (eg) 512B and 4K
logical sector sizes. This is needed because ATA drives are user-
replaceable and we don't know what could get plugged in.
* Add disk_get_log_sector_size() API (no-op for non-ATA storage)
* Mostly a no-op if MAX_LOG_SECTOR_SIZE is not enabled
* Sanity-check that storage's logical sector size is not larger
than what we're built for
NOTE: Other layers (eg ATA, FAT, etc) still need to be made aware of this.

* Support varying-sized logical sectors in a single build, instead
of a hardcoded SECTOR_SIZE.
* Properly truncate READ CAPACITY(10) if drive has over 2^32 sectors
And fix potential alignment issues
* Properly truncate READ_FORMAT_CAPACITY if drive has over 2^32 sectors
* Support READ CAPACITY(16)

....It's specified in 16-bit words, not bytes. So multiply it by 2.
(This hasn't been a problem in practice as everything uses 512B logical
sectors so far..)

* FLUSH_EXT is used if featureflag is set and we are using LBA48
(unconditionally used for CE-ATA on ipod6g)
* FLUSH is used if featureflag is set (ATA6+) or if device claims to be ATA5+
* Rename ata_disk_can_power_off() to ata_disk_can_sleep() as that is
what it actually tests for. Only use it to gate issuing the
STANDBY IMMEDIATE command.
* Restore behavior of ata_disk_is_active() to return 1 if drive is
"spinning" or powered up.
* Allow poweroff if drive claims PM support OR we are able to issue
FLUSH/FLUSH_EXT commands.
* Added ata_flush() to explicitly trigger a flush operation, and hook it
up to storage_flush() in the device shutdown path. (Flushes were
only previously used in the storage device power management path)
* After issuing all settings, re-issue IDENTIFY_DEVICE to make sure
it reflects everything we've enabled.
* Update manual section on Flash/SSD mods.

This is just to display the frequency correctly in the debug menu and prepare

This information is available in the RDA5802N or RDA5807 datasheet. I suspect
that register SYSCONFIG6 is not actually used by the tuner. Based on an
obscure statement in the datasheet, I guess SYSCONFIG5 is a frequency in Khz
called freq_direct that offsets the lower band frequency (56/67 MHz) but
1) it is not enabled (FREQ_MODE=0) and 2) it is not clear if this offset is
really just to avoid interference (ie the RF and IF are simply shifted by this
amount) or an actual offset.

The current code relies on the initial value of some RDS register(which is
documented) but this assumption will be broken when we start enabling RDS.
This commit changes the code to really read the chip ID, although it is more
involved.

ipod6g was configured with SECTOR_SIZE of 4096, but this ATA driver
unconditionally translated these to 512B operations on the actual
storage device.
Rockbox's storage layer already has robust support for "logical sectors
larger than physical storage sectors" through use of
MAX_LOG_SECTOR_SIZE. So switch to that mechanism, allowing the ipod6g
ATA driver to be simplified.
If we want to support drives with physical sector sizes > 512B, then
we need to port the MAX_PHYS_SECTOR_SIZE logic from the primary ATA driver.
Additional changes:
* Simplify MWDMA/UDMA selection logic
* Report CE-ATA mode in debug menu
* Use LBA48 commands only if drive is over 128GiB.
* Drop default sleep/poweroff time from 20s to 7s (matching main ATA driver)
Finally, the bulk of the changes are the first phase of a badly needed
style cleanup that made reading this driver a lot harder than it should
be. I intend to split this into a separate patch.

I'm 98% sure that the "byteswapped" value I saw was due to another bug
(bad PIO timings on ipods leading to data corruption) and none of the
growing pile of identify device data files that I have include the
backwards one.

The iPod 4g and color always ignored the very first
button press after booting, i.e. you needed to either
press another button or scroll for a bit first.
Not sure whether any other PP iPods exhibit the same
behavior, although it is not reproducible on an iPod
video.
This patch basically copies the code from FS#5230
that fixed unresponsive buttons whenever the HOLD
switch was turned off (committed as a5961c944b).

Basically, there are weak aliases for all possible IRQ handlers,
pointing at a NORETURN function. GCC complains that the aliases
don't have the same attribute, but that's actually what we want.

The flag would apparently make hardware accelerated

hardware acceleration, if the flag is missing.

The 12K-per-thread necessary on arm64 linux systems caused an
unnecessary 180K increase in RAM usage on the hibyos hosted ports. So
back off to the old size unless we know it was needed.

This allows callers to see if it's safe to enqueue something instead

Due to the heisenberg principle, we don't want to check the battery
level when the ATA drive is "spun up".
Unfortunately some ATA devices *cough most SD adapters cough* don't
support mandatory ATA power management commands like flushing caches and
(safely) shutting down so we have to leave them "spinning".
This leads to us never updating our battery status with these
out-of-spec devices. Work around this issue by having is_active() always
return false if that's what we have.

This option is especially useful for theme creators that want to create themes with lockscreens. When text is scrolling, it is breaking the lockscreen so setting this option to true prevent this. Text will continue to scroll normally in all other contexts.
