Allows for the i2c boilerplate to be shared between the M3K and
Shanling Q1 ports. M3K-specific quirks remain in button-fiiom3k.

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).

- Add support for skip and seek while the player is locked.
(Thanks to @bahus for the suggestion)
- Fix touch zones because the down button zone ended up being
a lot smaller than expected due to the touchpad's wonkiness.
Also added a visual display of the touchpad to its debug menu.
- Fixes the pictureflow keymap because it was mostly unusable.

Although data transfer is reliable with DMA, it seems to cause hangs
and lockups during the early stages of connection and it's not clear
what the cause might be.

This only required a minor patch to the usb-designware driver due
to DMA requiring physical addresses -- on the X1000, these differ
from virtual addresses so we have to do the usual conversion.
Both the mass storage and HID drivers work, but there are a few
issues so this can't be considered 100% stable yet.
- Mass storage might not be detected properly on insertion,
and USB has to be replugged before it shows up
- HID driver may occasionally panic or hang the machine

After conducting some simplistic tests, I found that the power usage
did not appear to be affected by the CPU frequency.
I tested by playing back a 44.1 KHz FLAC file on single track repeat,
and measured current with the AXP173's battery discharge current ADC.
The button and LCD backlights were set to always on. Headphones were
unplugged and the volume was muted to eliminate any influence from
the headphone amp.
On average the current usage was between 78-81 mA at 1008 MHz, 252 MHz,
and 112 MHz. If anything, 1008 MHz drew _less_ current than the lower
frequencies, by about 1-3 mA.
A possible explanation for this, assuming it's not just a bias of the
test, is that the CPU idle state saves so much power that it's better
to maximize the real time that the CPU spends idling. More systematic
testing is needed to confirm this.

* Cannot turn off the LCD directly (have to rely on backlight)
* Only insmod/rmmod the usb gadget modules if state changes

* HOME_DIR is now either "/" or special "<HOME>"
* target-specific "home dir path" is defined solely by PIVOT_ROOT
* PIVOT_ROOT path is now defined in toplevel config files
* Make Samsung YP-R0/R1 and SONY_NWZ use PIVOT_ROOT too
* Do not prepend PIVOT_ROOT path if the path already has it!
* Do not play these games for __PCTOOL__ builds

The Q and K have a slightly different case, but the hardware under the
shell is completely identical.
These models are rebadged versions:
* Hifiwalker H2 (== Q)
* AGPTek H3 (== K)
* Surfans F20 (== K)
Other notes:
* Significant improvements in the shared Hiby-platform launcher/loader
* SD card can theoretically be hot-swapped now
* Support external USB mass storage!
* Some consolidation of Hiby-platform targets
* Some consolidation of plugin keymaps
Todo/known issues:
* Keymaps need to be gone over properly
* Convert to HAVE_SCROLLWHEEL?
