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 DB410c (apq8016,
28nm-lp) and lightly tested on RB3 (sdm845, 10nm).
Changes since RFC:
- Reorder patches to move global clock patches in the beginning and
dtsi patches where they are required.
- remove msm_dsi_phy_set_src_pll() and guess src_pll_id using PHY usecase.
The following changes since commit a38fd8748464831584a19438cbb3082b5a2dab15:
