pinctrl: renesas: Minimize R8A7792 V2H PFC tables

Reduce the PFC tables by ifdeffing out pinmux settings which are
unlikely to be used by U-Boot. This helps reduce the size of the
bootloader in the 10 kiB range. This includes conditional build
of these PFC additions:

- CAN
- DU
- INTC
- MSIOF
- VIN
