From: Jose Marinho <jose.mari...@arm.com>
- Add the --prm flag to the GENFW_FLAGS
- Add the --no-gc-section to the linker flags so that apparently
unreferenced symbols are not prematurely removed from the .dll which
is used to generate the Prm module .efi.
- Force the linker to maintain the PrmModuleExportDescriptor symbol.
- Force the linker to maintain the PRM handler funtion's symbol.
