Support flashing image to BIOS flash, simple as that.

Implementation is going to be a bit tricky maybe. I'd like to investigate doing BIOS flashing when the host is on, and only giving it control of the flash when it is in the BIOS, and as a soon as it is done reading it don't have it own the BIOS anymore. That will most likely break user-mode BIOS flashing/dumping however.

Still, the BMC is the one that should own the chip, and restricting the host from updating it can be a good thing as well.

Maybe using device tree overlays could be a thing here. Add/remove the flash controller when the mux is changed.
