[Why]
In hdmi_mode_alternate_clock(), it adds an exception for VIC 4
mode (4096x2160@24) due to there is no alternate clock defined for
that mode in HDMI1.4b. But HDMI2.0 adds 23.98Hz for that mode.
[How]
Remove the exception
v2: Adjust the comment description of hdmi_mode_alternate_clock()
due to there is no more exception for VIC 4 mode.
