phy: cdns-dphy: Remove leftover code

The code in cdns-dphy has probably been part of a DSI driver in the
past. Remove DSI defines and variables which are not used or do not
actually do anything. Also rename cdns_dsi_get_dphy_pll_cfg() to
cdns_dphy_get_pll_cfg(), i.e. drop the "dsi", as it's not relevant here.
