[PATCH V2 7/7] ARM: dt: create a DT header for the GIC

[Stephen Warren]

From: Stephen Warren <swarren at nvidia.com>

The ARM GIC binding defines a few custom cells and flags for its IRQ
specifier. Provide names for those.

v2: No change.
v1: Moved header. Added include guard.
    (this patch was previously posted separately, hence there are
    changes in v1!)
