With the driver supporting multiple generations of hardware, some mold
has definitely grown over the code..

This series attempts to amend this situation a bit by commonizing some
code paths and fixing some bugs while at it.

Only tested on SM8250.

Definitely needs testing on:

- SDM845 with old bindings
- SDM845 with new bindings or 7180
- MSM8916
- MSM8996
