WM9081_BIAS_ENA is the bit[1] of WM9081_BIAS_CONTROL_1 register (05h).
Current code incorrectly write it to WM9081_VMID_CONTROL(04h) register.

VMID Divider Enable and Select is controlled by BIT[2:1] of WM9081_VMID_CONTROL
register (04h).
Current code reads wrong register (WM9081_BIAS_CONTROL_1) for setting
VMID 2*240k.

This initial conversion just moves the register init, regulator acquisition
and device verification out to the I2C probe(). Movement of other parts of
the driver like the GPIO and beep generation code will follow.

Now that the WM8996 driver is using the regmap API for register I/O we no
longer need the ASoC card to be active in order to interact with the chip.
In order to be more idiomatic for Linux move most of the existing probe()
function out into the I2C probe() function prior to registration with ASoC.
The IRQ and GPIO init will be moved separately as these are slightly more
involved.

Occasionally we may see an accessory reported before we have a stable
impedance for the accessory. If this happens then reread the status in
order to ensure that the handler can take the appropriate action for the
status change.

The thermal shutdown support in wm_hubs devices is tied to the speaker
drivers (which are the only high power subsystems within the device).
Ensure minimal current usage when the thermal shutdown support is not
required by disabling the circuit when the speaker drivers are powered
down.

Disable the thermal shutdown circuits for headphone and speaker when the
relevant outputs are not enabled in order to save current in idle modes.
Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
The WM9081 thermal shutdown is only effective when the speaker output is
enabled so disable it when that is not in use for a small current saving.

Having a separate list for amps is a little confusing now the official
driver model for them is the same as for other CODECs so let's sort them
into the CODEC list, but only do this for those that are actual CODEC
drivers so it's easier to remember which ones need updating.

Force MICBIAS on as well as SYSCLK as the WM8962 accessory detection can't
function without both. No point in making machine drivers manually enable
it.

Since we have code to automatically manage the start and stop of the FLL
based on the SYSCLK widget if SYSCLK is already enabled and the FLL is
configured then we need to start it up.
