From: Geert Uytterhoeven <geert+renesas@xxxxxxxxx>
Link the ARM GIC to the INTC-SYS module clock and the C4 power domain,
so it can be power managed using that clock in the future.
Note that currently the GIC-400 driver doesn't support module clocks nor
Runtime PM, so this must be handled as a critical clock.
