On R-Car H1 and Gen2, the SYSC interrupt registers are always configured using hardcoded values in platform code. For R-Car Gen2, values are provided for H2 and M2-W only, other SoCs are not yet supported, and never will be. Move this configuration from SoC-specific platform code to the rcar_sysc_init() wrapper, so it can be skipped if the SYSC is configured from DT. This would be the case not only for H1, H2, and M2-W using a modern DTS, but also for other R-Car Gen2 SoCs not supported by the platform code, relying purely on DT. There is no longer a need to return the mapped register block, hence make the function return void.
