StandaloneMM: Update permissions for Standalone MM drivers memory area
The StandaloneMM image executes in S-EL0 on reference Arm platforms
and is deployed by the trusted firmware as BL32 image. Memory for the
Standalone MM drivers is marked as RW+XN initially, allowing the
drivers to be loaded into the memory. Once loaded, the memory
attributes need to be changed to RO+XN for rodata sections and RO+X
for code sections.
Achieve this through the extra action 'UpdatePeCoffPermissions' to
request the privileged firmware in EL3 to update the permissions.
