Is it possible to handle this by inserting DAPM widgets for these
filters into the bypass paths and letting DAPM power them up? I'm also
wondering if with the new bias level management stuff which keeps the
codec in BIAS_ON while any DAPM widgets are powered some of the bypass
mode stuff can be removed or simplified?
I'm OK with the change if Peter acks it, I've not got detailed knowledge
of the TWL4030.
