[PATCH v3 0/2] Add mediatek codec mt6359 driver

Add mediatek codec (MT6359) driver

MT6359 support playback and capture feature.

On downlink path, it includes three DACs for handset, headset,
and lineout path. On unlink path, it includeds three ADCs for
main mic, second mic, 3rd mic, and headset mic.

By scenario, select *_MUX widget to create damp path.
And by select mic_type_mux to choose DMIC/AMIC/....

For example, select these MUX widget to create headset path
(1) DAC In Mux --> "Normal Path"
(2) HPL Mux --> "Audio Playback"
(3) HPR Mux --> "Audio Playback"

v3 changes:
	1. Remove calibration related functions.
	2. Conbined 'HPL Mux' and 'HPR Mux' to 'HP Mux'.
	3. Move the regulator_enable of 'vaud18' to the component probe.
	4. Fix some incorrect coding style.

v2 changes:
