regulator: wm8994: Pass descriptor instead of GPIO number

Instead of passing a global GPIO number for the enable GPIO, pass
a descriptor looked up from the device tree node or the board file
decriptor table for the regulator.

There is a single board file passing the GPIOs for LDO1 and LDO2
through platform data, so augment this to pass descriptors
associated with the i2c device as well.

The special GPIO enable DT property for the enable GPIO is
nonstandard but this was accomodated in
commit 6a537d48461deacc57c07ed86d9915e5aa4b3539
"gpio: of: Support regulator nonstandard GPIO properties".

ASoC: wm8994: Support constraining the maximum number of channels clocked

Some systems use the audio CODEC to clock a DAI with multiple data lines
in parallel, meaning that bit clocks are only required for a smaller number
of channels than data is sent for. In some cases providing the extra bit
clocks can take the other devices on the audio bus out of spec.

Support such systems by allowing a maximum number of channels to be
specified.

ASoC: wm8994: Support external capacitors on MICBIAS2 with jack detection

When an external capacitor is connected to MICBIAS2 on devices with
jack detection (which is not required but may be done in some systems)
then the loading may mean that better performance is obtained when
the microphone bias is enabled normally rather than using the low power
mode. Provide platform data allowing systems to indicate if they require
this.
