Panel replay was enabled by default in commit 5950efe25e
("drm/amd/display: Enable Panel Replay for static screen use case"), but
it isn't working properly at least on some BOE and AUO panels. Instead
of being static the screen is solid black when active. As it's a new
feature that was just introduced that regressed VRR disable it for now
so that problem can be properly root caused.

This 8.4 inch panel is integrated in the Ayaneo Kun handheld
device. The panel resolution is 2560×1600, i.e. it has
portrait dimensions.
Decoding the EDID shows:
Manufacturer: MSF
Model: 4099
Display Product Name: 'TV080WUM-NL0 '
Judging from the product name this might be a clone of a
BOE panel, but with larger dimensions.
Panel frequently shows non-functional backlight control. Adding
some debug prints to update_connector_ext_caps() shows that
something the OLED bit of ext_caps is set, and then the driver
assumes that backlight is controlled via AUX.
Forcing backlight control to PWM via amdgpu.backlight=0 restores
backlight operation.

[Why]
Like commit ec5fa9fcde ("drm/amd/display: Adjust the MST resume flow"), we
want to avoid handling mst topology changes before restoring the old state.
If we enable DP_UP_REQ_EN before calling drm_atomic_helper_resume(), have
changce to handle CSN event first and fire hotplug event before restoring the
cached state.
[How]
Disable mst branch sending up request event before we restoring the cached state.
DP_UP_REQ_EN will be set later when we call drm_dp_mst_topology_mgr_resume().

Cursors are always programmed independently of updates on other
planes. When atomic commits program cursor and surface updates
together the cursor update might be locked out by the surface
update and not take effect.
To combat this program cursor and surface updates together via
dc_update_planes_and_stream to ensure they can be applied
atomically.
When cursor updates come on their own use the old method
to program the cursor as dc_update_planes_and_stream isn't
handling this case correctly (yet), leading to a flickering
screen.

We're seeing issues when user-space tries to do an atomic update of
the primary surface, as well as the cursor. These two updates are
separate calls into DC and don't currently act as an atomic update.
This might lead to cursor updates being locked out and cursors
stuttering.
In order to solve this problem we want to separate the setting
and programming of cursor attributes and position. That's what
we're doing in this patch. The subsequent patch will then be
able to use the cursor setters in independent cursor updates,
as well as in atomic commits.
