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.

Thinkpad Helix 2 is a tablet PC, the audio is powered by Core M
broadwell-audio and rt286 codec. For all versions of Linux kernel,
the stereo output doesn't work properly when earphones are plugged
in, the sound was coming out from both channels even if the audio
contains only the left or right channel. Furthermore, if a music
recorded in stereo is played, the two channels cancle out each other
out, as a result, no voice but only distorted background music can be
heard, like a sound card with builtin a Karaoke sount effect.
Apparently this tablet uses a combo jack with polarity incorrectly
set by rt286 driver. This patch adds DMI information of Thinkpad Helix 2
to force_combo_jack_table[] and the issue is resolved. The microphone
input doesn't work regardless to the presence of this patch and still
needs help from other developers to investigate.
This is my first patch to LKML directly, sorry for CC-ing too many
people here.

codec driver and component driver has duplicated callback functions,
and codec side functions are just copied to component side when
register timing. This was quick-hack, but no longer needed.
This patch moves these functions from codec driver to component driver.

RT286_CBJ_CTRL1(0x4f) bit 10 is needed for headset capture. It
will be turned off when "VREF" widget is on and be turned on when
bias level is ON. It is odd. And if "VREF" is turned on in bias
level is ON, RT286_CBJ_CTRL1(0x4f) bit 10 will be turned off.
This patch move the bit control from rt286_set_bias_level and
rt298_vref_event to rt286_jack_detect. So it will be turned on
once a jack is plugged in.

RT286 can't do register reset. If the hardware power is still existing
in power off, rt286 will keep the register settings. So, we need to
restore the default register value in probe to make sure the cache value
is the same as the real register value.
