V1 : Following patchset add the support of ARM Firmware Framework protocol to MM communication.
Following chagnes are made to enable the support 1> Changed the FFA enable flag(PcdFfaEnable) to integer to enable it use in assembly. 2> Add the support to Reserved SP stack space and program in startup code. 3> Added ABI for enabling FFA protocol 4> Added conditional support in Standalone MM to parse DTB and populated configuration info required for FFA. 5> Added FFA support in MmCommunicationDxe module.
