pinctrl: renesas: Minimize R8A77965 M3-N 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: - Audio - CAN/CANFD - DU - INTC-EX - MSIOF - PWM - SSI - VIN Signed-off-by: Marek Vasut <marek.vasut+renesas@mailbox.org>
