bd32b43065 usb-flasher: Update stock firmware's USB product ID 
The third batch of review samples was flashed with a different stock
firmware, and advertised a different product ID.

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

cea046008f Increase the default flashing area size to 0x2000 
This does two things:
- more reasonable default because stock firmware size is larger than
  the previous default
- it will overwrite 0x3fff with 0xff, so that after flashing stock
  firmware the user firmware is automatically disabled

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.
