OMAP4: deactivate AESS OPP50
We currently do not support scaling to OPP50 on other domains than MPU.
Enabling OPP50 for ABE currently generates discrepancies between expected
clocks frequencies and breaks audio record.
This patch fixes audio record issue on current builds (tested on 4460 panda).
Another way to prevent scaling is to not plug the audio device_scale function.
