ARM: shmobile: r8a73a4 dtsi: Add SoC-specific irqc compatible property

The interrupt controller used the generic compatible property only.
Add the SoC-specific one, to make it future proof.

ARM: shmobile: r8a7740 legacy: Add missing INTCA clock for irqpin module

This clock drives the irqpin controller modules.
Before, it was assumed enabled by the bootloader or reset state.

ARM: shmobile: r8a7794: Reserve memory as other R-Car Gen2 SoCs

Other R-Car Gen2 SoCs such as r8a7790 and r8a7791 reserve
the top 256 MiB of memory for use with CMA. Adjust the
board-less r8a7794 code to do the same.
