amdfwtool: Allow the location to be a relative address
When the BIOS size is more than 32M, the physical address of EFS
header will be complicated, like 0xfe020000 or 0xfc020000. So we make
it simpler to allow to use relative address.
This CL works with https://review.coreboot.org/c/coreboot/+/69852
TEST=Result image is binary same on
