* Xiaomi's audio HAL uses the "echo-reference-voip speaker" path during voip
calls in speaker mode, while the CAF hal uses the "echo-reference-voip" path.
* That led to an echo in voip speaker calls since xiaomi appends speaker
to the path name and hence the echo reference wasn't set up properly, because
xiaomi did not apply their echo-reference edits to the default path.
* To fix this we can apply xiaomi's "echo-reference speaker" and
"echo-reference-voip speaker" as "echo-reference" and "echo-reference-voip".
* Remove the "echo-reference speaker" and "echo-reference-voip speaker" paths
because they are the same as "echo-reference" and "echo-reference-voip" and
even if the HAL will support speaker paths one day, it would not be needed for
us since we don't need to differ between speaker and no suffix.
