This also removes popp information from the RTAC remove

Regular audio playback is failing after kernel 3.0 upgrade
until unless hostless switch is renamed
The hostless mode switch name is currently same as back-end
AIF and new DAPM search logic in kernel 3.0 finds the route
entry for hostless pcm to slimbus Rx backend with "Switch"
as control word first. If switch is not on, it considers as
source and sink are not joined and playback fails
Hence hostless mode switch name had to be renamed to allow
both regular playback and hostless mode playback to work on
3.0 kernel

At the end of playback, framework asks CODEC to mute a particular
audio interface through digital mute callback. In our case, there
is no need to make this function callback available. At the same
time, this cause ADIE loopback not working because earpiece path
is muted. That's why we need to run hostless PCM to have the
framework unmute earpiece path.

The microphone bias used for headset microphone is also used for button
polling in case of headset. This causes fluctuation of current on the
headphone path, resulting in a periodic clicking noise.
Switching the microphone bias to VDDIO when headphone playback is in
progress and headset mic recording is not in progress avoids the click
noise problem

Audio hardware path can be started not only for audio playback/capture
but also voice call. ADM COPP is created through Q6ADM driver
when AFE port is started. For voice call use case, creating
ADM COPP in DSP wastes unnecessary memory resource. To create
ADM COPP only for audio playback/capture case, management logic
is moved to pcm routing driver which has information about session
ID of MultiMedia streams and state of audio back-ends. With this
information, pcm routing driver decides to start/stop ADM COPP.
