voicebus: Update the default vpmadt032 parameters.
Move the echo can channel parameters into a common location for both the
wcte12xp and wctdm24xxp drivers that use the voicebus module. This is intended
to make it clearer which differences are required between the clients.
Additionally, update the default parameters to the new recommended values.
