pinctrl: renesas: rzg2l: Add RZ/G3S support 

Add basic support for RZ/G3S to be able to boot from SD card, have a
running console port, and use GPIOs.  RZ/G3S has 82 general-purpose IO
ports.  Support for the remaining pin functions (e.g. Ethernet, XSPI)
will be added along with controller-specific support.
