In the current implementation, substring comparison
using device node name is used to find mdp node
during driver probe. Use compatible string instead
of node name to get mdp node from the parent mdss node.

Hi Dave & Daniel,
A few fixes for v5.15:
* Fix a new crash on dev file close if the dev file was opened when
GPU is not loaded (such as missing fw in initrd)
* Switch to single drm_sched_entity per priority level per drm_file
to unbreak multi-context userspace
* Serialize GMU access to fix GM
+ dri-devel, sorry hit 'send' too quickly

The current implementation supports a single DP instance and the DPU code will
only match it against INTF_DP instance 0. These patches extends this to allow
multiple DP instances and support for matching against DP instances beyond 0.
With that in place add SC8180x DP and eDP controllers.

As the Qualcomm DisplayPort driver only supports a single instance of
the driver the commonly used struct dp_display is kept in a global
variable. As we introduce additional instances this obviously doesn't
work.
Replace this with a combination of existing references to adjacent
objects and drvdat
Functions in the DisplayPort code that relates to individual instances
(encoders) are passed both the struct msm_dp and the struct drm_encoder.
But in a situation where multiple DP instances would exist this means
that the caller need to resolve which struct msm_dp relates to the
struct drm_encoder
As the following patches introduced support for multiple DP blocks in a
platform and some of those block might be eDP it becomes useful to be
able to specify the connector type per block.
Although there's only a single block at this point, the array of descs

Based on the removal of the g_dp_display and the movement of the
priv->dp lookup into the DP code it's now possible to have multiple
DP instances.
