Current r8a7795.dtsi defines audma -> ipmmu -> dma order.
Because of this order, dma can connect to ipmmu, but
audma can't connect to it.
This patch moves audma order as ipmmu -> dma -> audma.

Link the ARM GIC to the INTC-AP module clock, and add it to the SYSC
"always-on" PM Domain, so it can be power managed using that clock.

Note that currently the GIC-400 driver doesn't support module clocks nor
Runtime PM, so this must be handled as a critical clock.
