[PATCH 01/03] gpio: rcar: Use lazy disable and mask on suspend

[Magnus Damm]

From: Magnus Damm <damm@xxxxxxxxxxxxx>

Set the ->irq_enable() and ->irq_disable() methods to NULL
to enable lazy disable of interrupts. Also 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.
