mfd: Mask and unmask wm8350 IRQs on request and free
Bring the WM8350 IRQ API more in line with the generic IRQ API by masking and unmasking interrupts as they are requested and freed. This is mostly just a case of deleting the mask and unmask calls from the individual drivers. The RTC driver is changed to mask the periodic IRQ after requesting it rather than only unmasking the alarm IRQ. If the periodic IRQ fires in the period where it is reqested then there will be a spurious notification but there should be no serious consequences from this. The CODEC drive is changed to explicitly disable headphone jack detection prior to requesting the IRQs. This will avoid the IRQ firing with no jack set up.
