ASoC: da7218: Improve driver efficiency with regards to MCLK usage
Currently MCLK remains enabled during bias STANDBY state, and this is not necessary. This patch updates the code to handle enabling and disabling of MCLK, if provided, when moving between STANDBY and PREPARE states, therefore saving power when no active streams present.
