Hi folks, This series unfied LoongArch and MIPS's IOCSR functions and macros so they will expose same interface to arch-indenpendent drivers. This can reduce code deuplication, and also help my unifed IPI driver and MIPS extio driver effort. This is touching many sub-systems in once so might be hard to merge. Huacai, can you apply first three patch via loongarch-next tree. For last two patch maybe better merge them via a second PR after all subsystem PRs merged. No functional change so hope it's not too late for 6.12 :-) Please review.
