drm/msm: cache active displays within display manager
Update dsi driver to fill a provided array with display pointers
of all active dsi displays, and cache them within the display
manager structure.
This way, the display manager can simply look up the desired
display pointer based on a local index rather than asking the
dsi driver to perform a lookup each time and checking if it's
valid and active.
