ALSA: hda - Make the inv dmic handling for Realtek use generic parser

From what I can see, the generic parser is now good enough to handle
Realtek's inverted dmic handling, so let's remove the special handling
and use the generic parser instead.

- * Inverted digital-mic handling

- * First off, it's a bit tricky.  The "Inverted Internal Mic Capture Switch"
- * gives the additional mute only to the right channel of the digital mic
- * capture stream.  This is a workaround for avoiding the almost silence
- * by summing the stereo stream from some (known to be ForteMedia)
- * digital mic unit.
- *
- * The logic is to call alc_inv_dmic_sync() after each action (possibly)
- * modifying ADC amp.  When the mute flag is set, it mutes the R-channel
- * without caching so that the cache can still keep the original value.
- * The cached value is then restored when the flag is set off or any other
- * than d-mic is used as the current input source.
