ASoC: SOF: mediatek: remove unused variables

Merge series from Trevor Wu <trevor.wu@mediatek.com>:

There are some variables that are no longer being used because they
were declared for the deprecated memory layout. Currently, these code
sections confuse the users. Therefore, this series removes the code
that was implemented for those variables.
