drm/msm/dsi: Allow to specify dsi config as pdata 



Config autodetect based on DSI controller version is quite limited
since several qcom SoCs can integrate a DSI controller with the same
version, but with different config (io_offset, supplies, etc).

This change allows to specify dsi config via device data pointer.
config autodetect is still used in case data pointer is NULL.
