Ard Biesheuvel 2fe25a74d6 ArmPkg/MmCommunicationDxe: relay architected PI events to MM context
PI defines a few architected events that have significance in the MM
context as well as in the non-secure DXE context. So register notify
handlers for these events, and relay them into the standalone MM world.

Achin Gupta 4c2f32ed1a ArmPkg/Drivers: Add EFI_MM_COMMUNICATION_PROTOCOL DXE driver.
PI v1.5 Specification Volume 4 defines Management Mode Core Interface
and defines EFI_MM_COMMUNICATION_PROTOCOL. This protocol provides a
means of communicating between drivers outside of MM and MMI
handlers inside of MM.

This patch implements the EFI_MM_COMMUNICATION_PROTOCOL DXE runtime
driver for AARCH64 platforms. It uses SMCs allocated from the standard
SMC range defined in DEN0060A_ARM_MM_Interface_Specification.pdf
to communicate with the standalone MM environment in the secure world.

This patch also adds the MM Communication driver (.inf) file to
define entry point for this driver and other compile
related information the driver needs.
