From: Lad Prabhakar <prabhakar.mahadev-lad.rj@xxxxxxxxxxxxxx>
On the RZ/G2UL SoC we have less number of pins compared to RZ/G2L and also
the pin configs are completely different. This patch makes sure we use the
appropriate pin configs for each SoC (which is passed as part of the OF
data) while configuring the GPIO pin as interrupts instead of using
rzg2l_gpio_configs[] for all the SoCs.
