[PATCH 02/05 v2] gpio: rcar: Enable mask on suspend

[Magnus Damm]

From: Magnus Damm <damm@xxxxxxxxxxxxx>

Now when lazy interrupt disable has been enabled in the driver
then extend the code to set IRQCHIP_MASK_ON_SUSPEND which tells
the core that only IRQs marked as wakeups need to stay enabled
during Suspend-to-RAM.

Tested on the Lager board with GPIO-keys and Suspend-to-RAM.
