Etienne Carriere 4921e7452c pinctrl/nomadik: MASK_ON_SUSPEND 
ux500 machines performs pins (GPIO) reconfiguration when entering
in the suspended mode. This reconfiguration aims at reaching an ultra
low power HW configuration.

Due to this HW reconfiguration, some HW devices can change of HW state
and have their output signals at level that could generate IRQs.

If the non-wakeup IRQs are disabled but not yet masked (delayed interrupt
disable feature from the generic irq layer), effective interrupts reach
the system only because the system attempt to enter the suspended mode.

To prevent such IRQs to trig, all irq chips embedded in ux500 platform
should enable their IRQCHIP_MASK_ON_SUSPEND flag.
