Peter Ujfalusi 029c2cfde9 drm/omap: DMM: Check for DMM readiness after successful transaction commit
[ Upstream commit b7ea6b286c ]

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.
