Series drm/msm/dsi: refactor MSM DSI PHY/PLL drivers | expand

Commit Message

Dmitry Baryshkov March 24, 2021, 3:18 p.m. UTC 
All PHY drivers would map dsi_pll area. Some PHY drivers would also
map dsi_phy area again (a leftover from old PHY/PLL separation). Move
all ioremaps to the common dsi_phy driver code and drop individual
ioremapped areas from PHY drivers.
