Replace the wm831x-local IRQ infrastructure with genirq, allowing access
to the diagnostic infrastructure of genirq and allowing us to implement
interrupt support for the GPIOs. The switchover is done within the
wm831x specific IRQ API, further patches will convert the individual
drivers to use genirq directly.

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.

during suspend (saving substantial power) and the runtime use of the

Since platform_device_add_data copies the passed data, the allocated
subdev_pdata is never freed. A simple fix would be to either free subdev_pdata
or put it onto the stack. But since the pcf50633 child devices can rely on
beeing children of the pcf50633 core device it's much more elegant to get access
to pcf50633 core structure through that link. This allows to get completly rid
of pcf5033_subdev_pdata.

Rather than open coding individual IRQs in each function which
manipulates them store data for IRQs in a table which is then
referenced in the users.
This is a substantial code shrink and should be a performance win in
cases where only a single IRQ goes off at once since instead of
reading four of the second level IRQ registers for each interrupt
we read only the sub-registers which have had an interrupt flagged.
