[PATCH v2 0/3] arm64: Realtek RTD1295 IRQ mux

This series adds two IRQ muxes for the Realtek RTD1295 SoC.

There being no public source code for RTD1295, the implementation is based on
register offsets seen in the vendor DT, split up into two separate nodes,
as well as code from QNAP's rtk119x GPL code dump.

v2 does various cleanups, including limiting the serial quirk to the iso mux.

More experimental patches at:

Have a lot of fun!


v1 -> v2:
* Rebased, avoiding dependency on reset series for DT nodes
* Don't forward set_affinity to GIC (Marc)
* Added more spinlocks (Marc)
* Code cleanups
* Investigated quirk
* Fixed spinlock initialization (Andrew)
