pinctrl: sh-pfc: r8a7795: Add support for INTC-EX IRQ pins
Most pins on the r8a7795 SoC can be configured in GPIO mode for interrupt and GPIO functionality, while a couple of them can also be routed to the INTC-EX hardware block (formerly known as IRQC). On r8a7795 the INTC-EX hardware handles pins IRQ0 -> IRQ5 and this patch adds support for them to the PFC driver as "intc_ex_irqN". Tested on r8a7795 Salvator-X with an external loop back adapter on EXIO_D that connects pin 9 (IRQ2/GP2_02) and pin 26 (ExA22/GP2_06).
