Add irqchip specific flags for msmgpio irqchip to mask non wakeirqs during
suspend and mask before setting irq type.

Masking before changing type should make sure any spurious interrupt is not
detected during this operation.

This seems like two different problems and both descriptions are thin on
details imho.  If you're respinning the series I would appreciate if you
improved this.
