Use mechanical switch on the phone jack to detect headset/headphone
insertion and removal. Mechanical switch is beneficial to avoid fake
button press and high impedance microphone headset detection.

If HPHL and HPHR have relatively high impedance, internal MBHC HPHL
trigger cannot trigger so results in headphone/headset detection
failure.
Utilize MIC trigger as well as HPHL trigger in order to detect headphone
and headset which have high impedance on headphone line.

The compander system is intended to increase the dynamic
range of an input signal. But for the wcd9310 codec,
this feature is to use companding in a novel way in the DAC
converter path to increase the signal noise ratio.
The change is to add the compander support to wcd9310
codec. The dynamic compander enable/disable during stream
playback is not supported.

The current core assumes TABLA as the only codec driver registering.
To support single binary for multiple targets its essential that
we remove this restriction and move to a generic framework
to support multiple codec. This can be done by moving all codec
specific code to dedicated codec driver and use core driver to probe
the codec based on slimbus device id and do generic setup for the
codec. This also helps to have same boards with different flavours
of codec variants.
The WCD9XXX family of codecs share the initial codec register
mapping which holds the Slimbus device id to identify the
codec existing on the target.Core driver now registers the
codec device based on this check.
