Similar to what commit 1e3ad571 (ASoC: Remove redundant -codec from
WM8776 driver name) does for wm8776 driver, this patch does the same
thing for cs4270 driver.

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.

This minimises the chance of any external capacitors that are fitted
being discharged into headphones as they insert.

The WM8775 is register compatible with the WM8776 so can be supported with
the same driver though it is an ADC only part. Add the device ID to the
WM8776 driver, further updates will be added in the future.

While it matches the current code only bringing the device out of reset
isn't actually doing what the function says so make sure we set the GPIO
high before we pull it low.
