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).
