snd_soc_open() will trigger pm_runtime resume() which will then enable the regulator and initialization. So we should make sure the MCLK is enabled before this resume(). Previously we let the machine driver get the clock and enable it in its probe(). However, considering about power saving, it'll be better to enable it when it's going to be used and disable it after using. So this patch just simply adds clk_get() and clk_enable() to WM8962 driver. Meanwhile, it marks clock pointer to NULL if no clock assigned to it so it will not break any current function.
