[PATCH 1/3] dt-bindings: interrupt-controller: arm,gic-v3-its: Add quirk to support 32 bit addressable range

[adrianhoyin . ng]

From: Adrian Ng Ho Yin <adrianhoyin.ng@xxxxxxxxxx>

Add quirk to configure gfp flags to only allocate buffers within 32 bit
addressable range to support devices that cannot support the full 64 bit
address range.
