Series drm/msm/dpu: add support for independent DSI config | expand

Move setting up encoders from set_encoder_mode to
_dpu_kms_initialize_dsi() / _dpu_kms_initialize_displayport(). This
allows us to support not only "single DSI" and "bonded DSI" but also "two
independent DSI" configurations. In future this would also help adding
support for multiple DP connectors.

This looks quite neat now,so i am okay with this version of it:

Just a suggestion, since we are only supporting two dsis so far, do we 
need
an extra variable to get the other DSI? Can't we just do 
priv->dsi[DSI_1]?
as usually DSI_0 is the master

I still hope to fix "swap links in bonded DSI mode" (in other words DSI 
0 being clock master, but driving right half of the screen) one day. 
Thus I don't think we should enforce DSI_0/DSI_1 here.
