irqchip/bcm2836: Enable SKIP_SET_WAKE and MASK_ON_SUSPEND

Browse source 
The BCM2836 interrupt controller doesn't provide any facility to configure
the wakeup sources. That's the reason why the driver lacks the
irq_set_wake() callback for the interrupt chip.

Enable the flags IRQCHIP_SKIP_SET_WAKE and IRQCHIP_MASK_ON_SUSPEND so the
interrupt suspend logic can handle the chip correctly equivalently to the
corresponding bcm2835 change (9a58480e5e ("irqchip/bcm2835: Enable
SKIP_SET_WAKE and MASK_ON_SUSPEND").
