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

From: Magnus Damm <damm@opensource.se>

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 KZM9D board with GPIO-keys.
