Various bugfixes and improvements to the cs42l42 codec driver.

Clocking bugfixes:
  - Remove any use of MCLK > 12.288 MHz because it isn't possible to switch
    between the low and high frequency ranges on-the-fly

  - Prevent the PLL configuration being written while the PLL is running
  - Correctly set the MCLK for the sample rate converters

ASP bugfixes:
  - Ensure the TX (capture) ASP is properly configured when recording
    mono audio.

Other bugfixes:
  - Prevent NULL pointer deref if there is an interrupt before soc
    component probe

Code cleanup:
  - Remove the unused runtime suspend/resume functions.
  - Remove some code made redundant by an earlier patch

Improvement:
  - Add ALSA control for HP path attenuation. Previously this was
    always set to -6dB with no way for the user to configure it.

  - Add ALSA control to disable the soft volume ramp at the start of
    audio.
