[PATCH v2 2/2] ArmPkg/Include: Add SVC function IDs for Management Mode.

[Supreeth Venkatesh <supreeth.venkatesh@arm.com>]

SVCs are in the range 0xC4000060 - 0xC400007f.
The functions available to the secure MM partition:
1. Signal completion of MM event handling.
2. Set/Get memory attributes for a memory region at runtime.
3. Get version number of secure partition manager.

Also, it defines memory attributes required for set/get operations.
