sc7180: Add display 10nm phy & pll programming support
Adds basic headers as well as source required for display dsi 10nm phy & pll programming. Changes in V1: - add struct overlays to model hardware registers. - remove typedef structures. - remove dead code such as dual dsi,split config etc. Changes in V2: - remove panel related header files. - update the bitclock calculation using edid parameters. - add phy timing calculation function. - update copyright license. Changes in V3: - update the mdss clock structure. - remove dsi_phy_configinfo_type struct. - remove unused struct fields. Changes in V4: - update clock apis. - remove unused structures.
