The following series fixes the HandsfreeL/R pop removal sequence:
The pop removal is moved from the MUX_E to PGA_E DAPM control and also
the sequence is modified to match with the sequence described in the TRM.
Note, that the power-down sequence is not described in the TRM, it has been
implemented in a way that it should make sense.

HandsetL/R mute: Since all bits are needed for the pop removal and they have to
modified in a strict order/timing:
I have added SW_SHADOW non HW register. This register at the moment only handles
the HandsfreeL/R mute.
