Pinmux information should be provided by the pinmux driver, not arch code. Make it possible to do so by supporting pinmux information passed through the driver_data field in the platform ID table. Platform data will remain supported until all arch code has been converted. Rename the sh_pfc_platform_data structure to sh_pfc_soc_info to reflect this.
