ASoC: wm8904: fix wrong outputs volume after power reactivation
Restore volume after charge pump and PGA activation to ensure
that volume settings are correctly applied when re-enabling codec
from SND_SOC_BIAS_OFF state.
CLASS_W, CHARGE_PUMP and POWER_MANAGEMENT_2 register configuration
affect how the volume register are applied and must be configured first.
