drm/msm/dsi: Add support for qcm2290 dsi controller
QCM2290 MDSS includes a Qualcomm DSI controller v2.4.1. Since this
controller version is not SoC specific, and already assigned to sc7180
for auto configuration, we rely on DSI block specific compatible
string "qcom,dsi-ctrl-6g-qcm2290", and use the device's data to point
to the right dsi config handler.
