From: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>

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.
