Allow battery debugging to be enabled via serial port
Fix incorrect battery critical LED state
Change W to mW in battery debug output to make the scale clearer
Add debounce for the thermal alarm signal and enable a new LED state when triggered. (Alternating power LED and red battery LED)
Blink code for high battery current prior to stop mode (Alternating Green/Yellow)
Blink code for exiting stop mode while power is off (Alternating Green/Red)

Fix logic bug in ext power detect after runin discharge. Machines turning off runin discharge could fail to sense external power.
Print ACR value and SOC when going into stop mode
Refactor critical and low flag handling to fix corner cases. There were several corner cases where you could get the previous code to display the wrong LED state.
Add support for GP LiFePO4 batteries. There are few around the Twine offices.
Turn off battery state debugs in LiFePO4 code
kbdwatch: wait longer after seeing SOC_SLEEP to release flow-control. Fixes a lockup on 1Ghz MMP3.

Check battery EEPROM bank 0 values and fix them if wrong
Detect bad ACR register reads from the battery due to ESD and discard them
Generate 2 wake up interrupts to the SoC on resume. One to make it wake up and then a 2nd to actually make it start executing. Works around resume problems.

Change battery over temperature indicator to be a pulse of dark (both LEDs off) rather than a pulse of red. Red is now exclusively for errors.
Fix typo in IO map causing LV_SET code to mess with EC_IRQ.
