MBHC (MultiButton Headset Control) support is available in pm8921 in two
blocks, one to detect mechanical headset insertion and removal and other
block to support headset type detection and 5 button detection and othe
features like impedance calculation.
This patch adds support to:
1> Support to NC and NO type of headset Jacks.
2> Mechanical insertion and detection of headset jack.
3> Detect a 3 pole Headphone and a 4 pole Headset.
4> Detect 5 buttons.
Tested it on DB410c with Audio Mezz board with 4 pole and 3 pole
headset/headphones.

This patch adds bindings in DT to provide required micbias voltage which
could be specific to board. With this new binding, now the mic bias
voltage is left at hardware default value if the device tree does not
specify any mic bias voltage value. Correct micbias value is required
for mbhc buttons to work.

This patch move the codec reset code from dai ops to codec probe, so
that the codec is not held in reset when headset detection block is
still active.
Without this patch the codec block will be in reset as long as its not
actively used, which means headset events will not be functional if the
codec dai is not actively used. Point to note is that the headset
detection blocks will work in low power when there is no active audio
usecase and switch to micbias source when audio usecase is active.
Existing dapms should put the codec in low power state anyway when there
is no audio usecase.

Declare snd_soc_codec_driver structures as const as they are only passed
as an argument to the function snd_soc_register_codec. This argument is
of type const, so declare the structures with this property as const.
In file codecs/sn95031.c, snd_soc_codec_driver structure is also used in
a copy operation along with getting passed to snd_soc_register_codec.
So, it can be made const too.

Current hdmi-codec driver is using hdmi_controls for "ELD" control.
But, hdmi-codec driver might be used from many HDMIs. Thus, we need
to correspond device number, otherwise we will receive below error.

jd_mode=2). It overrides the whole pdata fields, so pass it
