arm64: dts: renesas: falcon-cpu: Use INTC_EX for SN65DSI86
The INTC block is a better choice for handling the interrupts on the V3U
as the INTC will always be powered, while the GPIO block may be
de-clocked if not in use. Further more, it may be likely to have a lower
power consumption as it does not need to drive the pins.
Switch the interrupt parent and interrupts definition from gpio1 to
irq0 on intc_ex, and configure the PFC accordingly.
