Turns out they did not swap the stereo switch lines on us,
so this setting isn't really useful. Repurpose it to allow
the user to force the device into headphone or line output mode.
Note that settings other than "Automatic" will cause jack detection
to not work.
Default Automatic.

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.

Hopefully this should cover our bases so we can change
the behavior of the stereo switch to keep line out working
when they change the hardware on us!

Add HW volume control via ES9018K2M, and reorganize
eros_qn_codec.c/.h, audiohw-erosqnative.c.
This automatically detects the presence of the new DAC and
uses its hardware volume scaling. If not present, use same
SWVOL we have been using so far.
Add debug menu readout of SWVOL/I2C result.
Break out es9018k2m stuff into its own file so that
maybe it can be useful to other ports.
Note that we may need to get smarter about detecting the DAC
type if/when another model emerges.

The newer players have some changed hardware, but most importantly
the line out now appears to be routed through the stereo switch
instead of being hardwired directly off the DAC.
Disable muting the headphone amp, enable switching the stereo switch,
and rename some of the GPIOs to be more generic since the DAC,
headphone amp, and stereo switch all appear to have changed.

An oversight on my part meant that setting channel balance to
100% L or 100% R would mute both channels - this logic will
prevent that.

A small negative offset seems to silence all
play/pause clicking on the PCM5102A.
Also adding PCM soft muting, and muting the headphone amp
when the headphones are detected as removed. This has been
tested to not cause any unintended side effects on the
line out.
Also confirmed the numerical dB values are (approx.) correct.

What works:
- LCD: 16-bit RGB565
- all buttons, including scrollwheel
- SD Card
- Battery level and charging/not charging status
- USB
- audio
- sample rate switching
- HP / LO detect, with "safe" fixed LO volume -
LO volume will only be put to user-defined max volume
if headphones are not present.
- rtc
- Plugins build, tried a couple and they seem OK
- Bootloader, installable to nand via usbboot
What doesn't work:
- Dual Boot
- power on/off has intermittent, low volume audio click
(sometimes it's completely silent, sometimes there's
a click)
- Audio uses 16-bit volume scaling, so clicking/popping
is pretty bad at lower volumes - need 32 bit volume
scaling, 24 bit I2S data
- USB HID keys not yet defined
- no jztool support
Unknowns:
- Stereo Switch pins: Direction select, AC_DC
(probably not even hooked up)
- What is the actual purpose of the Stereo Swtich?
- How does the bluetooth module connect?
"Someday" stuff:
- get LCD working at higher bit depth
- Bluetooth
