Bug description:
  [Impact]
  Like GPIO controlled LED, COEF controlled LED also need LED class
  support, in order to be used by SoF driver.

  [Fix]
  Convert all HDA vendor-specific LED control to generic LED class.

  [Test]
  After applying the patch series, COEF controlled LED is exported under
  /sys/class/leds/, so SoF driver now can control the micmute LED.

  Also verified on GPIO based micmute LED, it also works fine.

  [Regression Potential]
  Low. Though there are 13 patches, most of them are straightforward
  conversion.
