Move the pm-rcar driver from arch/arm/mach-shmobile/ to drivers/soc/renesas/, and its header file to include/linux/soc/renesas/, so it can be shared between arm32 (R-Car H1 and Gen2) and arm64 (R-Car Gen3). Rename it to rcar-sysc as it's really a driver for the R-Car System Controller (SYSC). Kill the intermediate PM_RCAR config symbol, as it's not user configurable anymore, and to prepare for SoC-specific make rules. Add the missing #include <linux/types.h> to rcar-sysc.h, which was exposed by different include order.
