feat(gicv3): validate multichip data for GIC-700
This patch introduces support to validate the GIC-700 multichip data
structure passed by the platform.
GIC-700 provides support for SPI ID 4096 to 5119. Platforms using the
GIC-700 in a multichip configuration can enable these SPI IDs. The
driver needs to validate the data before using it and this patch
implements the support.
