After the commit abc0b1447d4974963548777a5ba4a4457c82c426
("drm: Perform basic sanity checks on probed modes"), proper
clock-frequency becomes mandatory for validating the mode of panel.
The display does not work if there is no mode validated. Also, this
clock-frequency must be set appropriately for getting required frame
rate.
