pinctrl: sh-pfc: Stop calling gpiochip_add_pin_range() on DT platforms
On platforms where the PFC/GPIO controller is instantiated from DT, the mapping between GPIOs and pins is set up using the "gpio-ranges" property in DT. Hence stop setting up the mapping from C code on DT platforms. This code is still used for SH or ARM-legacy platforms.
