Merge series "Make genaral and simple for new sof machine driver" from David Lin <CTLIN0@nuvoton.com>:

The series of features will make general and simple for new sof machine driver.

David Lin (2):
  ASoC: nau8825: add set_jack coponment support
  ASoC: nau8825: add clock management for power saving
