When no controls are assigned in the parser (e.g. no analog path),
spec->kctls.list is still NULL.  We need to check it before passing to
snd_hda_add_new_ctls().

In some cases, we want to manipulate the auto_pin_cfg table before
passing to snd_hda_gen_parse_auto_config() (e.g. Realtek SSID check
code fiddles with the headphone pin).   Also passing ignore_pins just
for snd_hda_parse_pin_defcfg() isn't good.

In this patch, snd_hda_gen_parse_auto_config() is changed to receive
the auto_pin_cfg table to be parsed.  The passed auto_pin_cfg table
must have been initialized (typically by calling
snd_hda_gen_parse_auto_config()) beforehand by the caller.

Also together with this change, spec->parse_flags is also removed.
Since this was referred only at the place calling
snd_hda_parse_pin_defcfg(), no longer needed to be kept in spec.

Finally the whole generic parser code in Realtek driver is moved into
hda_generic.c so that it can be used for generic codec driver.
The old dumb generic driver is replaced.  Yay.

The future plan is to adapt this generic parser for other codecs,
i.e. the codec driver calls the exported functions in generic driver
but adds some codec-specific fixes and setups.

As of this commit, the complete driver code is still duplicated in
Realtek codec driver.  The big code reduction will come from now on.

This patch extends the capability of the auto-mic feature.
Instead of limiting the automatic input-source selection only to the
mics (internal, external and dock mics), allow it for generic inputs,
e.g. switching between the rear line-in and the front mic.

The logic is to check the attribute and location of input pins, and
enable the automatic selection feature only if all such pins are in
different locations (e.g. internal, front, rear, etc) and line-in or
mic pins.  That is, if multiple input pins are assigned to a single
location, the feature isn't enabled because we don't know the
priority.

(You may wonder why this restriction doesn't exist for the headphone
 automute.  The reason is that the output case is different from the
 input: the input source is an exclusive selection while the output
 can be multiplexed.)

Note that, for avoiding regressions, the line-in auto switching
feature isn't activated as default.  It has to be set explicitly via
spec->line_in_auto_switch flag in a fixup code.

Put INPUT_PIN_ATTR_FRONT after INPUT_PIN_ATTR_REAR, and define
INPUT_PIN_ATTR_LAST to point to the last element.

This is a preliminary work for cleaning up Realtek auto-mic parser.
In the auto-mic implementation, the front panel is preferred over the
rear panel.  By arranging the attr definitions like in this commit, we
can simply use sort() for figuring out the priority order.

So far we create only "Capture Volume" and "Capture Switch" controls

There are a few more cases where we can assign "Master" mixer element

Also, when vmaster hook is present, avoid "Master" but assign "PCM"

Now we reached to the final big piece of parser rewrite: the input
paths.  While the old parser code assumes the more-or-less direct and
similar connections from input pin to ADC, the new code handles the
complete input paths.  The capture source is switched by simple calls
of activate_path() function.

The parsing of capture volume and capture switches is, however, not
fully generalized.  It assumes that amps are available in the vicinity
of ADCs (in three depth).  This isn't perfect but it should cover all
codecs I know of.

Also, this commit removes some NID mapping of capture-related controls
temporarily for simplicity.  It'll be restored in later commits.

For optimizing the verb executions, a new mechanism to cache the verbs
and amp update commands is introduced.  With the new "write to cache
and flush" way, you can reduce the same verbs that have been written
multiple times.

When codec->cached_write flag is set, the further
snd_hda_codec_write_cache() and snd_hda_codec_amp_stereo() calls will
be performed only on the command or amp cache table, but not sent to
the hardware yet.  Once after you call all commands and update amps,
call snd_hda_codec_resume_amp() and snd_hda_codec_resume_cache().
Then all cached writes and amp updates will be written to the
hardware, and the dirty flags are cleared.

In this implementation, the existing cache table is reused, so
actually no big code change is seen here.  Each cache entry has a new
dirty flag now (so the cache key is now reduced to 31bit).

As a good side-effect by this change, snd_hda_codec_resume_*() will no
longer execute verbs that have been already issued during the resume
phase by checking the dirty flags.

connections in a more generic way.
