ASoC: cs35l56: Add control to read CAL_SET_STATUS
Create an ALSA control to read the value of the firmware CAL_SET_STATUS control. This reports whether the firmware is using a calibration blob or the default calibration from the .bin file. The firmware only reports a valid value in this register while audio is actually playing and the internal PLL is locked to the audio clock. Otherwise it returns a status of "unknown".
