MLK-10830 ASoC: imx-wm8960: audio mclk should be enabled early to avoid jack detect error
Audio mclk should be enabled early to avoid jack detect error.
It will playback from speaker in the first 2 seconds, then switch to
headphone. Steps to reproduce this issue:
1. plug out headphone and playback a wav.
2. stop playback and wait for at least 5 seconds, then plug in headphone
and playback a wav.
And set TOCLKSEL (bit1 R23) to get faster jack detect response.
