This is an RFC attempt to restructure MSM DSI PHY drivers. What started
as an attempt to grok the overcomplicated PHY drivers, has lead up to
the idea of merging PHY and PLL code, reducing abstractions, code
duplication, dropping dead code, etc.
The patches were mainly tested on RB5 (sm8250, 7nm) and lightly tested on RB3
(sdm845, 10nm), DB410c (apq8016, 28nm-lp).
The following changes since commit fe07bfda2fb9cdef8a4d4008a409bb02f35f1bd8:
