pinctrl: renesas: rzg2l: Add RZ/G2UL support

RZ/G2UL SoC has fewer pins compared to RZ/G2L and the port pin
definitions are different compared to RZ/G2L.

This patch adds a new compatible to take care of these differences by
adding r9a07g043_data with r9a07g043_gpio_configs and
rzg2l_dedicated_pins.common.
