Subject: [PATCH v1 6/6] gpio: realtek-otto: Add RTL931x support

The RTL931x SoC series has support for 32 GPIOs, although not all lines
may be broken out to a physical pad.

The GPIO bank's parent interrupt can be routed to either or both of the
SoC's CPU cores by the GIC. Line-by-line IRQ balancing is not possible
on these SoCs.
