Add bin2pgd tool
...
This is used by the vendor's flashing tool. It's ROM image + option
ROM image appended (256 bytes).
Option ROM contains some flags and configuration data for the MCU.
Things like oscillator configuration, HW reset pin enable, data EEPROM
enable, etc.

Revert "firmware: Make interrupt signal shorter (10us)"
...
The longer duration is actually required, likely due to debouncing
applied on the SoC side. Even 50us was unreliable.
This reverts commit 3b723583e7

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.

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

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.
