[PATCH 07/10] drm/msm/dsi: Switch the QCM2290-specific compatible to index autodetection

[Konrad Dybcio]

Now that the logic can handle multiple sets of registers, move
the QCM2290 to the common logic and mark it deprecated. This allows us
to remove a couple of structs, saving some memory.

Fixes: ee1f09678f14 ("drm/msm/dsi: Add support for qcm2290 dsi controller")
