Daniel Vetter a095caa7f5 drm/atomic-helper: roll out commit synchronization 
To facilitate easier reviewing this is split out from the overall
nonblocking commit rework. It just rolls out the helper functions
and uses them in the main drm_atomic_helper_commit() function
to make it clear where in the flow they're used.

The next patch will actually split drm_atomic_helper_commit() into
2 pieces, with the tail being run asynchronously from a worker.

v2: Improve kerneldocs (Maarten).

v3: Don't convert ERESTARTSYS to EINTR (Maarten). Also don't fail if
the wait succeed in stall_check - we need to convert that case (it
returns the remaining jiffies) to 0 for success.

v4: Switch to long for wait_for_completion_timeout return value
everywhere (Maarten).

v5: Fix miscaped function in kerneldoc (Maarten).
