Nishanth Menon 5e3bd996d2 arm64: dts: ti: k3-am64: Fix gic-v3 compatible regs 
commit de60edf1be upstream.

Though GIC ARE option is disabled for no GIC-v2 compatibility,
Cortex-A53 is free to implement the CPU interface as long as it
communicates with the GIC using the stream protocol. This requires
that the SoC integration mark out the PERIPHBASE[1] as reserved area
within the SoC. See longer discussion in [2] for further information.

Update the GIC register map to indicate offsets from PERIPHBASE based
on [3]. Without doing this, systems like kvm will not function with
gic-v2 emulation.
