The driver includes linux/irqchip/arm-gic-v3.h which pulls in headers
which are available only on ARM and ARM64, on other architectures the
headers are not present and the driver fails to build. This driver is
used only on ARM64 hardware, isolate its build only to ARM64 to avoid
build failures on other architectures.

V2: This is a rework of PCI: rcar-gen4: Inline GIC_TRANSLATER offset macro
    which isolates the driver build to ARM64 via Kconfig instead:
