Check for the ES9018K2M dac in the bootloader for
hw1/hw2 devices. Assume that all devices newer than
hw2 have ES9018K2M DAC unconditionally.
All devices will now report the correct hw revision
in the debug menu under Device Data.
Add devicedata.version field, current version 0.
Rename device_data.lcd_version to device_data.hw_rev.
hw2 devices with older bootloaders which ID as hw1 are special-
cased to keep using hwvol on them. They should still upgrade though.

Support hw4 units with AXP2101 PMU
Bootloader successfully compiles and loads onto device.
The LCD appears to be identical to hw3 units.
Scroll wheel and buttons work
Audio output works, including volume.
HP/LO detect works
Rockbox build is generic
GPIO gating logic seems to be working as intended now.
- Added new GPIO definitions - some significant overlaps with pins
from previous hardware revisions...
- Added some GPIO definitions for older players we didn't know about
- Add register definitions for AXP2101 from datasheet
(these are very different from AXP192!)
- Add AXP2101 regulator definitions, need to support multiple step
sizes per regulator.
- Verify AXP2101 voltage set multi-range logic
- Verify AXP2101 voltage get multi-range logic
- Make AXP2101 its own driver
- AXP2101 driver should be "minimally viable", though I think
there is some extra functionality that could be implemented.
- Disabling the coulomb counter stuff - we could maybe make
the E-Gauge work for the same purpose, but it only appears to
be used on the debug screen at the moment so it doesn't seem
like it's worth the effort.
- Found new button GPIOs
- Found error in my GPIO setting logic, blue light works now!
- Set LDO/DCDC output voltages to OF's settings, as far as
I can tell.
- Determined we probably want TCS1421_CFG1:0 to be 0x00,
for UFP behavior
- Tested this rb build with both old and new bootloaders on hw1.5,
hw2, hw4 in as many configurations as I can think of, works across
the board.
- Bootloader can install itself on hw4, so nand chip isn't novel
- Uninstallation file can be made by patcher script, works on hw4
- Installation file can be made by patcher script, works on hw4
- Added HW4 to rbutil, manual

Remove the battery power ADC since it's not used right now,
and seems to fluctuate too rapidly to be of much use.

This caused LCD problems on the ErosQ, where the screen would
go white until being put through a sleep/wake cycle. The exact
reason for this isn't obvious, but the problem didn't exist
prior to the AXP driver rewrite.
The two dependent changes,
42999913ba - x1000: Increase USB current limit to 500 mA at all times
90dd2f84a9 - x1000: Correctly limit USB charging current
ended up bringing the USB charging situation back to where it
was prior to the rewrite, so the cleanest option is to revert
the whole lot.
This reverts commit 42999913ba.
This reverts commit 90dd2f84a9.
This reverts commit 2d89143962.

I noticed a few mistakes in the old driver code and it was in
need of an overhaul anyway... I decided to scale things back,
simplify the code and remove most of the debug menus, netting
a nice code size savings.
One new feature is an advanced debug menu which is accessible
by recompiling the code with AXP_EXTRA_DEBUG. It adds quite a
bit of code size and isn't useful other than for development
so it must be manually enabled by editing the source.

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).
