Olivier Martin 919697ae6c ArmPkg/ArmGic: Added GICv3 specific definitions 
ARM GICv3 specification introduces some new components and registers.
This patch adds their definitions.

The most important GICv3 component is the GIC Redistributor. It supports
LPIs (Locality-specific peripheral Interrupt), 8+ CPU configuration.
Some GIC distributor registers have moved to the GIC redistributor.

Ard Biesheuvel 37ec4d9af7 ArmPkg/ArmGicLib: select GICv2 mode if SRE is present but unavailable 
Even if the CPU id registers indicate hardware support for the
System Register interface to the GIC, higher exception levels
may disable that interface and only allow access through MMIO.

So move the enabling of the SRE bit to the GIC version detection
routine: if we trigger an exception, we would have anyway at a
later stage, so the net effect is the same. However, if setting
the bit doesn't stick, it means we can switch to MMIO and proceed
normally otherwise.
