drm/msm/dpu: Drop max_mixer_width and MAX_HDISPLAY_SPLIT | expand

Message

Currently, the DPU driver bases LM reservation off of the maximum
supported width for the layer mixer and an arbitrary MAX_HDISPLAY_SPLIT.
However, these limits are not hardware limits meaning that a single LM
can support higher resolutions.

Switch to basing LM reservation off of PINGPONG and DSC encoder hardware
limits.
