Ard Biesheuvel 8659306a2e ArmPkg/ArmGicDxe: Expose HardwareInterrupt2 protocol 
The existing HardwareInterrupt protocol lacked a means to configure the
level/edge properties of an interrupt.  The new HardwareInterrupt2
protocol introduced this capability.
This patch updates the GIC drivers to provide the new interfaces.
The changes comprise:
  Update to use HardwareInterrupt2 protocol
  Additions to register info in ArmGicLib.h
  Added new functionality (GetTriggerType and SetTriggerType)

The requirement for this change derives from a problem detected on ARM
Juno boards, but the change is of generic (ARM) relevance.

This commit is in response to review on the mailing list and, as
suggested there, rolls Girish's updates onto Ard's original example.

Evan Lloyd b0393756d6 ArmPkg: Tidy GIC code before changes. 
This change is purely cosmetic, to tidy some code before change.
Mods involve:
    Re-order #includes
    Reformat comments.
    Use ns consistently (always "100ns" not sometimes "100 nS")
    Split overlength code lines.
    Make protocol functions STATIC.
    Remove "Horor vacui" comments.
    Rationalize GIC register address calculations
    Replace explicit test and assert with ASSERT_EFI_ERROR.

Heyi Guo 599f004b27 ArmPkg/Gic: Fix boundary checking bug 
mGicNumInterrupts is the total number of interrupts, so the interrupt
ID equal to mGicNumInterrupts is also invalid.

Olivier Martin 69b5dc9f8e ArmPkg/ArmGic: Move the installation and the registration to InstallAndRegisterInterruptService() 
It will allow reusing the same code for GICv2 and GICv3 only drivers.
