Revert "Add HAL API for enabling DSDS"

This reverts commit ee5b898af7d37326238cf281948409a9fc4b1684.

Reason for revert: <This should be added once HAL implementations are done, also it's causing failures when merging to AOSP, so the changes might not be safe. These changes are not required for the HAL changes anyways.>
