amd/pi/hudson: Add alternate method for including amdfw
For systems using Chrome OS, place the amdfw outside of cbfs control.
The firmware must go to a fixed position at an offset of 0x20000 into
the flash device.
Potentially improve by adding a warning or error message for the
condition when sizeof(amdfw) + sizeof(cbfs and metadata) > sizeof(flash).
