[PATCH 6.12.y-cip 00/18] Add ICU support for RZ/T2H and RZ/N2H SoCs

This patch series adds support for the ICU block, including
software-triggered interrupts and error interrupts, as found in the
Renesas RZ/T2H and RZ/N2H SoCs.

Patches 1 and 2 fix s2idle resume handling in the CPG driver.

Patches 3 and 4 are preparatory patches needed for patch 5.

Patch 5 implements the resume behavior that fixes s2idle resume over NFS
for RZ/T2H.

Patches 6 to 18 are simple mainline backports.
Patch 9 required a change to match the current definition of
IRQCHIP_MATCH().
Patch 11 required a conflict fix because of the above change.
Patch 17 required a conflict fix in the dts includes.
