sh: sh7720: Add pin control resources
Add memory resources for the pin control platform device to let the sh-pfc driver ioremap() registers properly instead of evily casting register physical addresses to virtual addresses. The memory resource address range has been extracted from the config and data registes lists in the sh-pfc driver. Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>
