Some DSI host versions are implemented on multiple SoCs which use
vastly different register maps. 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.

Tested on SM6115P Lenovo Tab P11 and SM8350 PDX215
