For Baytrail (Valleyview) and Braswell (Cherryview), only the HDMI codec is
in the display power well while the HD-A controller isn't. So the controller
flag 'need_i915_power' is not set to release the display power after probe,
and the codec flag 'link_power_control" is set to request/release the display
power via bus link_power ops.

This patch can improve power saving for Intel platforms on which only the
display audio codec is in the shared i915 power well:
- Add a flag "need_i915_power" to indicate whether the controller needs the
i915 power well.
- The driver will always request the i915 power when probing the controller
and codecs if AZX_DCAPS_I915_POWERWELL is set (either the controller or a
codec needs this power).
- If the controller needs the i915 power, the power will be held after probe
until the controller is runtime suspended or S3. If the controller doesn't
need the power, the power will be released the after probe, and a codec
that needs the power can request/release the power via bus link_power ops.
Background:
- For Haswell/Broadwell, which has a separate HD-A controller for display audio,
both the controller and the display codec are in the i915 power well.
- For Baytrail/Braswell, the display and analog audio share the same HDA
controller and link, and only the display codec is in the i915 power well.
- For Skylake, the display and analog audio share the same HDA controller but
use separate links. Only the display codec is in the i915 power well. And in
legacy mode we take the two links as one. So it can follow Baytrail/Braswell.

Originally hda_bus takes its own ops (hda_bus_ops) to allow different
controller drivers giving individual implementations of PCM
attachment, etc. But this never happened and we finally merged both
codec and controller helper codes. Thus there is no merit to keep the
indirect accesses to functions via hda_bus_ops.

Some BIOS version of Fujitsu Lifebook T731 seems to set up the
headphone pin (0x21) without the assoc number 0x0f while it's set only
to the output on the docking port (0x1a). With the recent commit
[03ad6a8c93: ALSA: hda - Fix "PCM" name being used on one DAC when
there are two DACs], this resulted in the weird mixer element
mapping where the headphone on the laptop is assigned as a shared
volume with the speaker and the docking port is assigned as an
individual headphone.
This patch improves the situation by correcting the headphone pin
config to the more appropriate value.

Currently, snd_hdac_power_up()/down() helpers checks whether the codec
is being in pm (suspend/resume), and skips the call of runtime get/put
during it. This is needed as there are lots of power up/down
sequences called in the paths that are also used in the PM itself. An
example is found in hda_codec.c::codec_exec_verb(), where this can
power up the codec while it may be called again in its power up
sequence, too.
The above works in most cases, but sometimes we really want to wait
for the real power up. For example, the control element get/put may
want explicit power up so that the value change is assured to reach to
the hardware. Using the current snd_hdac_power_up(), however,
results in a race, e.g. when it's called during the runtime suspend is
being performed. In the worst case, as found in patch_ca0132.c, it
can even lead to the deadlock because the code assumes the power up
while it was skipped due to the check above.
For dealing with such cases, this patch makes snd_hdac_power_up() and
_down() to two variants: with and without in_pm flag check. The
version with pm flag check is named as snd_hdac_power_up_pm() while
the version without pm flag check is still kept as
snd_hdac_power_up(). (Just because the usage of the former is fewer.)
Then finally, the patch replaces each call potentially done in PM with
the new _pm() variant.
In theory, we can implement a unified version -- if we can distinguish
the current context whether it's in the pm path. But such an
implementation is cumbersome, so leave the code like this a bit messy
way for now...

Like the previous patches, this patch converts also to the regmap, at
this time, the cached verb writes are the target. But this conversion
needs a bit more caution than before.
- In the old code, we just record any verbs as is, and restore them at
resume. For the regmap scheme, this doesn't work, since a few verbs
like AMP or DIGI_CONVERT are asymmetrical. Such verbs are converted
either to the dedicated function (snd_hda_regmap_xxx_amp()) or
changed to the unified verb.
- Some verbs have to be declared as vendor-specific ones before
accessing via regmap.
Also, the minor optimization with codec->cached_write flag is dropped
in a few places, as this would confuse the operation. Further
optimizations will be brought in the later patches, if any.
This conversion ends up with a drop of significant amount of codes,
mostly the helper codes that are no longer used.
