pinctrl: renesas: r8a77951: Add R8A774E1 PFC support

Browse Source 
Renesas RZ/G2H (r8a774e1) is pin compatible with R-Car H3 (r8a77951),
however it doesn't have several automotive specific peripherals. Add
a r8a77951 specific pin groups/functions along with common pin
groups/functions for supporting both r8a77951 and r8a774e1 SoC.

PFC changes are synced from mainline linux-5.9 commit
bbf5c979011a ("Linux 5.9").

Support pin multiplexing control on Renesas RZ/G2H R8A774E1 SoCs.
The driver is controlled by a device tree node which contains both
