gpio-rcar: R-Car GPIO IRQ share interrupt

commit c234962b808f289237a40e4ce5fc1c8066d1c9d0 upstream.

R-Car H1 or Gen2 GPIO interrupts are assigned per each GPIO domain,
but, Gen1 E1/M1 GPIO interrupts are shared for all GPIO domain.
gpio-rcar driver needs IRQF_SHARED flags for these.
This patch was tested on Bock-W board
