ASoC: da7219: Make more efficient use of MCLK within driver
Currently, if the driver has control of MCLK then it remains enabled as long as the codec is in STANDBY or above. The MCLK is only really required in STANDBY when a 3-pole jack is inserted and the HP detect procedure is required to run. This patch updates the code to enable/disable the MCLK when moving between the STANDBY and PREPARE bias level, and when a 3-pole jack is inserted and HP detection is required, thus saving power at all other times.
