394af632aa firmware: Allow to read/write single registers from a charger 
This code uses existing system command functionality. The I2C
registers are placed in front of system command register, to
allow for a single transaction proxied I2C A reads/writes.

Not tested, yet.

bd69a00f7a common: Improve crc8 generation 
Start with 0xff instead of 0x00, so the CRC will be nonzero (and length
dependent) for data that is all zeroes.

Remove unnecessary masking, since `crc` is already an 8-bit integer.

3b723583e7 firmware: Make interrupt signal shorter (10us) 
This is long enough, comparable to 100kHz I2C speeds.

2fbc2e057e firmware: Implement scanning block 
This allows to disable the keyboard. The firmware will never scan
for keys pressed in this mode, and it will powerdown the MCU most of the
time.

134b4b6a8b firmware: Move more of the USB shutdown control to usb_enable/usb_disable 
- make sure USB resources are re-enabled before jumping to bootloader
- make sure all USB resources are disabled prior to jumping to user fw

6a5fe581b9 Implement flashing over I2C and user/stock firmware support 
I2C register layout changed a bit to make various operations easier
to implement in FW and for the user.

Flashing/debugging tools now share more code. Firmware is now more
configurable (it's now possible to compile-out various features).

Self-testing for column-shorts is implemented.

Firmware is optimized for low power consumption.

bca8c47f46 Implement polled mode and key bitmap change signalling via external interrupt 
- this firmware consumes about 4-5 mA (can be probably made lower)
