When using ROM Armor, the AMD_BIOS_APOB_NV BIOS directory table
entry needs to be marked as writable. Add support for marking
BIOS directory table entries as writable and set all BIOS directory
files to RO, except for AMD_BIOS_APOB_NV (type 0x63), which is
written at end of coreboot based on the FMAP.
TEST=ROM Armor 3 enabled system can write APOB through PSP mailbox
interface. When the writable bit is not set cannot write APOB
through mailbox interface.
