Add synchronization support between clients that operate on different
modes, i.e. synchronous or asynchronous. The synchronous client will
momentarily switch to asynchronous if any asynchronous transmission is
scheduled.

This patch introduces a sysfs group entry for the UFS health descriptor
parameters. The group adds "health_descriptor" folder under the UFS driver
sysfs entry (/sys/bus/platform/drivers/ufshcd/*). The parameters are shown
as hexadecimal numbers. The full information about the parameters could be
found at UFS specifications 2.1.

When plane is detached from crtc in one atomic commit and then
attached to another crtc in the next atomic commit, the second
plane state swap will happen when the first commit is still running
in the previous crtc's worker thread, which will result in two
threads programming the same plane and run into undeterministic
state.
Fix is to add plane_mask check before state swap, together with
crtc_mask check. This will make sure there is no pending worker
thread working on the same plane.

HDMI 2.0 compliance E-DDC test requires the DDC
signal timings to meet a minimum threshold to pass

matching the requirement.
Adjust the DDC settings to meet the threshold and
also make sure to leave the remaining bits of DDC
speed register untouched.

Handle debugfs override edid and firmware edid at the low level to
transparently and completely replace the real edid. Previously, we
practically only used the modes from the override EDID, and none of the
other data, such as audio parameters.
This change also prevents actual EDID reads when the EDID is to be
overridden, but retains the DDC probe. This is useful if the reason for
preferring override EDID are problems with reading the data, or
corruption of the data.
Move firmware EDID loading from helper to core, as the functionality
moves to lower level as well. This will result in a change of module
parameter from drm_kms_helper.edid_firmware to drm.edid_firmware, which
arguably makes more sense anyway.
Some future work remains related to override and firmware EDID
validation. Like before, no validation is done for override EDID. The
firmware EDID is validated separately in the loader. Some unification
and deduplication would be in order, to validate all of them at the
drm_do_get_edid() level, like "real" EDIDs.
v2: move firmware loading to core
v3: rebase, commit message refresh

drawobj_destroy_sync() tries to cancel all pending sync events
by taking local copy of pending list. In case of sync point timestamp
event, it goes ahead and accesses context's events list assuming that
event's context would be alive.
But at the same time, if the other context, which is of interest for
these sync point events, can be destroyed by cancelling all
events in its group.
This leads to use-after-free in drawobj_destroy_sync() path.
Fix is to give the responsibility of putting the context's ref count
to the thread which clears the pending mask.
