> Drivers that switch between interrupt and polled completions don't need
> the mask write flushed to the device; the disabled state already
> keeps their handler from running and a late interrupt is replayed on
> enable. Add an optional irq_chip::irq_mask_noflush() callback, falling
> back to irq_mask(), and disable_irq_noflush() to mask through it right
> away rather than lazily.
