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). The patch 'clk: fixed: add devm helper for clk_hw_register_fixed_factor()' is already a part of mainline as of 5.12-rc1, but is included here for completeness to fix compilation issues (as msm-next is based on 5.11-rc5). Changes since v2: - Drop the 'stop setting clock parents manually' patch for now together with the dtsi changes. Unlike the rest of patchset it provides functional changes and might require additional discussion. The patchset will be resubmitted later. Changes since v1: - Rebase on top of msm/msm-next - Reorder patches to follow logical sequence - Add sc7180 clocks assignment - Drop sm8250 clocks assignment, as respective file is not updated in msm/msm-next 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.
