[ Upstream commit 14d9a37c952588930d7226953359fea3ab956d39 ]

This reverts commit f4b34faa08.

Since commit f4b34faa08 ("drm/imx: Annotate dma-fence critical section in
commit path") the following possible circular dependency is detected:

[    5.001811] ======================================================
[    5.001817] WARNING: possible circular locking dependency detected

[    5.001957]
[    5.001957] which lock already depends on the new lock.
...

Revert it for now.

Tested on a imx6q-sabresd.
