ASoC: wcd934x: force the wdsp clock to be ungated

Browse Source 
The wcd934x codec DSP (WDSP) has clock gate that can be controlled by
driver or the hardware controller to ungate the clock to the WDSP. Due
to issues seen during back to back testing, it is found that the clock
is not properly ungated by the hardware controller and can cause hang
on the WDSP. Fix this issue by forcing the clock to be ungated from the
driver always.
