In APM X-Gene, GIC register space is 64K aligned while the sizes mentioned
in the dt are 4K aligned. This breaks KVM when kernel is built with 64K page
size due to size alignment checking in vgic driver for VCPU Control and
VCPU register.
This patch corrects the sizes to be inline with the hardware spec.
