util/amdfwtool: Add option to indicate uncompressed BIOS binary
amdfwtool always assumes that the PSP BIOS binary (type 0x62 BIOS
directory entry) is always compressed. On boards using vboot, sometimes
PSP BIOS binary is uncompressed - specifically when CBFS verification is
enabled and verified boot starts in bootblock. Add an option to indicate
PSP BIOS binary is uncompressed.
BUG=b:261792282
TEST=Build Skyrim BIOS with x86 verstage and CBFS Verification enabled.
Boot to OS.
