v2 -> v3: - Merge with [1], I should have done that earlier.. - Squash 6115 compatible patches into one - Pick up tags (except Rob's ack in 6115 compatible addition, as it was changed) - Use b4 (sorry if you got an incomplete set of messages before..)

This messes with our current assumptions of being able to map {dsi0, dsi1} to {reg0, reg1}. Solve that by adding a way of specifying multiple sets of base registers and try comparing them against the register specified in DT until we find a match. This removes the need for the QCM2290-specific compatible which was used in the SM6115 DT (which uses DSIv2.4.1, just like SC7180). The series also takes care of that.
