mfd: wm8994: Inline register I/O functions
Since the register I/O functions are all simple wrappers for the regmap

mfd: wm8994: Emulate level triggered interrupts if required
The interrupt controller on the wm8994 series of devices requires a level

mfd: wm8994: Store platform data in device
This is better style as platform data is supposed to be discardable after

mfd: wm8994: Update to fully use irq_domain
Take advantage of the new regmap irq_domain support to dynamically
allocate interrupts, using regmap_irq_get_virq() rather than irq_base
to look up the interrupts. This means that most users should not need
to specify an irq_base at all.

mfd: Don't suspend WM8994 if the CODEC is not suspended
ASoC supports keeping the audio subsysetm active over suspend in order
to support use cases such as audio passthrough from a cellular modem
with the main CPU suspended. Ensure that we don't power down the CODEC
when this is happening by checking to see if VMID is up and skipping
suspend and resume when it is. If the CODEC has suspended then it'll
turn VMID off before the core suspend() gets called.

mfd: Add initial WM8958 support
The WM8958 is a derivative of the WM8994 which is register compatible
with the addition of some extra features, mostly in the CODEC side.
The major change visible at the MFD level is that rather than a single
DBVDD supply we now have three separate DBVDDs so we must request and
enable a different set of supplies.

while allowing for systems that do not have an interrupt hooked up.
Wrapper functions are provided for the IRQ request and free to simplify
the code in consumer drivers when handling cases where IRQs are not
set up.
