irqchip/irq-vt8500: Split up ack/mask functions
vt8500_irq_mask() really does the ACK for edge triggered interrupts and the
MASK for level triggered interrupts. Edge triggered interrupts never
really are masked as a result, and there is unnecessary reading of the
status register before the ACK even though it's write-one-to-clear.
Split it up into a proper standalone vt8500_irq_ack() and an unconditional
vt8500_irq_mask().
No Fixes tag added, as it has survived this way for 15 years and nobody
complained, so apparently nothing really used edge triggered interrupts
anyway.
