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.
