drm/omap: DMM: Check for DMM readiness after successful transaction commit
Check the status of the DMM engine after it is reported that the
transaction was completed as in rare cases the engine might not reached a
working state.
The wait_status() will print information in case the DMM is not reached the
expected state and the dmm_txn_commit() will return with an error code to
make sure that we are not continuing with a broken setup.
