- Missing mutex unlock in nand_open()
- SET_FEATURE command incorrectly issued as a read operation
- Inverted protection bits, not sure how that happened...
- Block erase skipped ahead by a wrong amount, causing erases
spanning multiple blocks to erase the wrong blocks
This code was buggy as hell... it's in need of a major overhaul.
It's not very flexible or reliable, and access to the flash is
useful during development of a new port, even if not useful once
the port is complete.

On devices that can assign interrupt IN, bulk IN and bulk OUT endpoints
this change results in the serial interface working out of the box on
Linux and Windows. On Linux it is registered as ttyACM device and on
Windows it is assigned a COM port number.
On devices that cannot assign the interrupt IN this change won't have
any effect.
Implement minimum required interface control requests. Respond with
whatever line coding was set to make terminal programs happy.

Disabling double buffering results in expected CPPI TX behaviour. With
the double buffering enabled, sending single ZLP resulted in two ZLPs
being available. The two ZLPs is problematic because this causes Windows
to reset USB device after failed SCSI command.
The problematic sequence on Windows 10 was as follows:
* Host sends SCSI Mode Sense(6) Informational Exceptions Control(0x1C)
* Device sends ZLP
* Device sends command failed response
With endpoint double buffering enabled the ZLP was read twice by host.
As host was expecting command response on the second read (and got ZLP
instead), host attempts recovery by resetting USB device and retrying.

Correctly set endpoint maximum packet size so host will not consider
end of transfer after receiving first packet when transfer is larger
than 64 bytes (at High Speed the endpoint max packet size was set to
64 but according to descriptor it is 512).
Split DMA transfers up to CPPI_MAX_FRAG so we get single interrupt
after each call to tnetv_cppi_send().

Avoids having to #define the names of GPIO pin interrupt handlers,
as they can now be set at runtime instead.

The GPIO API was pretty clunky and pin settings were decentralized,
making it hard to see what was happening and making GPIO stuff look
like a mess, frankly.
Instead of passing clunky (port, pin) pairs everywhere, GPIOs are now
identified with a single int. The extra overhead should be minimal as
GPIO configuration is generally not on a performance-critical path.
Pin assignments are now mostly consolidated in gpio-target.h and put
in various tables so gpio_init() can assign most pins at boot time.
Most drivers no longer need to touch GPIOs and basic pin I/O stuff
can happen without config since pins are put into the right state.
IRQ pins still need to be configured manually before use.

The old name was a bit misleading. AXP173 is sort of the lowest common
denominator of a series of related chips. The M3K uses an AXP192 which
has a few extra features vs. the AXP173.
New voltage regulator stuff was added for the sake of the Shanling Q1
native port (that player also uses an AXP192).

Some audiohw API calls are shared between playback and recording,

Clearing recoverzap parameter exists the Recovery Mode. This makes it
possible to run Rockbox on Sansa Connect without relying on original
Linux firmware.
Enable write-through cache on flash memory as write-back complicates
handling without any real benefits. The flash memory accepts commands
as series of writes at predefined addresses, so it is important that
the cache does not interfere with the writes.

Motivation: turns out the DMA in the M3K's MSC controller is buggy,
and can't handle unaligned addresses properly despite the HW docs
claiming otherwise.
Extending the FAT driver bounce buffering code is the easiest way
to work around the problem (but probably not the most efficient).
