Subject: drm/msm/dsi: Use msm_clk_get in dsi_get_config
Git-commit: 29a1157ceba2bf885479d6dcd2933a6b0778266b
Patch-mainline: v4.17-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166
We try to get the interface clock in dsi_get_config early during DSI's
component bind. Try getting both the "iface" and "iface_clk" clock name
variants so that we are compatible with both new and legacy DT.
