Bump version to 20210107

As my fellow team members correctly pointed out, it is indeed 2021.

I would like to state that I am not living in the past and with not a
single fibre of my body want that 2020 isn't over, yet.

I think I need a second coffee this morning.

PC Engines: Force flashing for APUs with very old firmware

This is necessary to force flashrom to overwrite the firmware
even when the BIOS identifies as "APU*" (uppercase), but we
expect it to be "apu*" (lowercase).
