ASoC: wm8978: Use devm_regmap_init_i2c()

devm_regmap_init_i2c() is device managed and makes error
handling and code cleanup simpler.

ASoC: wm8994: Stop mic detection whenever we detect an open circuit

Jack detection will not do anything to help us detect a microphone when
there is a fault in the cable and the debounce we have is enough to avoid
getting an intermediate result so halt microphone detection when we detect
that one is not present.

ASoC: wm8994: Simplify button detection code

Currently the WM8994 driver allows the WM8958 microphone detection code to
be replaced in its entirety, providing a default implementation. This
doesn't actually reflect the needs of users well. They generally wish to
replace only the accessory identification parts of the algorithm (eg,
using an external GPIO to provide the equivalent of the JACKDET support in
the WM1811A).

In preparation for supporting these users better refactor the existing code
so that we have separate identification and button detection callbacks,
selecting between them rather than using the mic_detecting flag in the
existing callback. This also simplifies the code by introducing a more
explicit state machine for the detecting and button states.

In anticipation of future refactoring the callback is left in the signature
for wm8958_mic_detect(), it will be removed at a later stage.

ASoC: wm8994: Check jack is inserted when handling mic IRQ

If we've got jack detection support then check that the jack is still
inserted when handling a mic IRQ in order to avoid transient reports
caused by shorts during the removal process as the two interrupts race
with each other.

ASoC: zoom2: Remove HS mux GPIO handling to avoid kernel crash due to BUG_ON()

The machine driver try to use GPIO15 of twl4030 for HS MUX which supposed to
select between TWL's HSOL/R and tlv320aic3254's HPL/R.
The TWL's GPIO allocated dynamically so the (OMAP_MAX_GPIO_LINES + 15) is no
longer valid GPIO number causing a kernel crash due to BUG_ON()
Also the current machine driver supports only TWL audio currently: there is
no need to control the GPIO.

Change davinci_config_channel_size() to derive the values for XSSZ and
XROT in DAVINCI_MCASP_[RT]XFMT_REG from the configured word length
rather than hard-coding them in a switch/case block.

Also, by directly passing the word length to
davinci_config_channel_size(), we can get rid of the
DAVINCI_AUDIO_WORD_* enum.
