Split WM1A/WM1Z because they don't have the same KAS. On newer devices, the KAS
is actually 64 bytes, not 60. The strange thing is that "get_dnk_nvp kas" returns
60 bytes whereas "get_dnk_prop kas" returns 64, not sure why.

It doesn't work properly and interferes with the power button in the keymap.
Rework WPS keymap a bit to make single-tap power emulate lock.

Basically, existing sizes apply for <= 48KHz audio. Up to 96K,
we double the mix buffer. up to 192K, we double it again.
Will help reduce the interrupt load and overall latency, keeping it
roughtly constant as a function of time, regardless of bitrate.
(It is acutally a fixed-size buffer, statically-allocated to handle the
worst-case bitrate the player supports. However, at runtime if we are
using a lower bitrate we will only use a portion of it in order to keep
latancies down)

Unsure why this is happening, but now we detect and recover errors at
startup.
Also clean up the mismash of printf(), DEBUGF(), etc in favor of panicf() for the really serious stuff and logf() for everything else.

Note: PCM mix buffer sizes are _way_ too small for these high bitrates
(We really need to make the mixer stuff use dynamic buffer sizes based
on the bitrate. Maybe pre-allocate a max size based on upper bitrate limit,
but use only part of it at lower bitrates? So we can have sane latency..)

* xduoo x3ii/x20: Better line out support
* less granular volume settings (too many steps before)
* Better handling of swiching sample rates
* Log actual sample rate in debug menu

* Kill LCD when turning off the backlight
* Fix logic errors in lcd_enable() calls
* Use ioctls instead of sysfs to twiddle lcd enable

* SAMPR_CAPS_ALL -> SAMPR_CAPS_ALL_48/96/192
* All targets claiming SAMPR_CAPS_ALL now get appropriate subset
* No need to explicitly define HAVE_PLAY_FREQ
* Rates that are a multiple of 44 or 48KHz can be used for playback
Inspired by a patch by Roman Stolyarov, but substantially rewritten by myself.

Can be disabled at runtime by setting hold switch.
Boosts sysbench sequential write performance by 34-58%

* DMA Bulk IN (ie our TX) results in sequential transfers 33-68% faster.
* DMA Bulk OUT (ie RX) is mostly stripped out due to complete brokenness.
* Interrupt and control endpoints remain PIO-driven.
Other improvements:
1) Use consistent endpoint references (no magic numbers)
2) Greatly enhanced logging
3) DMA support can be compiled out completely
4) Setting lockswitch will disable all DMA operations at runtime
5) Much more robust error checking and recovery
