ArmPkg/Include: Add standard SMC function IDs for MM interface.
This patch adds a list of function IDs that fall under the standard
SMC range as defined in [1]
SMCs associated with Management Mode are in the range 0xC4000040 -
0xC400005f (64 bit) and 0x84000040 - 0x8400005f (32 bit).
The function(s) available to the normal world:
1. Request services from the secure MM environment using MM_COMMUNICATE.
It also defines MM return codes.
