Abstracts the hardware control of the physical address region 0xC0000-0xFFFFF.
The EFI_LEGACY_REGION2_PROTOCOL is used to abstract the hardware control of the memory
attributes of the Option ROM shadowing region, 0xC0000 to 0xFFFFF.
There are three memory attributes that can be modified through this protocol: read, write and
boot-lock. These protocols may be set in any combination.
