drivers: pfc_rcar: do MMIO mapping inside driver

Browse source 
Add MMIO mapping for PFC Renesas driver in order to avoid
mappings inside mmu_regions.c file.

Add a new system init function pfc_rcar_driver_init to PFC
Renesas driver for invoking a memory mapping macro.
Note: PFC Renesas driver doesn't use Zephyr Device Model.
