ASoC: wm8903: Fix the bypass to HP/LINEOUT when no DAC or ADC is running
commit f1ca493b0b5e8f42d3b2dc8877860db2983f47b6 upstream.
The Charge Pump needs the DSP clock to work properly, without it the
bypass to HP/LINEOUT is not working properly. This requirement is not
mentioned in the datasheet but has been confirmed by Mark Brown from
Wolfson.
