pinctrl: renesas: Add Kconfig symbol for conditional build of full PFC tables

By default the pin multiplexing tables used by U-Boot are reduced
to keep the size of the bootloader low. This option allows build of
full pin multiplexing tables the same way they are included in the
Linux kernel. This includes pin multiplexing options for Audio, CAN,
CANFD, DU, INTC, INTC-EX, MSIOF, PWM, SSI, for which there is no
U-Boot driver. This option is disabled by default.
