Add the RPC pins/groups/functions to the R8A77970 PFC driver.
They can be used if an Octal-SPI flash or HyperFlash is connected.
Based on the patch by Dmitry Shifrin <dmitry.shifrin@xxxxxxxxxxxxxxxxxx>.
Signed-off-by: Sergei Shtylyov <sergei.shtylyov@xxxxxxxxxxxxxxxxxx>

The patch is against the 'sh-pfc' branch of Geert's 'renesas-drivers.git' repo.
Changes in version 2:
- fixed up the initializer for rpc_ctrl_mux[];
- added Geert's tag.
