sh-pfc: Use pinmux identifiers in the pin muxing API
The PFC core exposes a sh_pfc_config_gpio() function that configures
pinmuxing for a given GPIO (either a real GPIO or a function GPIO).
Handling of real and function GPIOs belong to the GPIO layer, move the
GPIO number to mark translation to the caller and rename the function to
sh_pfc_config_mux().
