drm/meson: fix TMDS clock filtering for DMT monitors
DMT monitors does not necessarely report a maximum TMDS clock
in a VSDB EDID extension.
In this case, all modes are wrongly rejected, including
the DRM fallback EDID.
This patch only rejects modes whith clock > max_tmds_clock if
the max_tmds_clock is specified. This will only reject
4:2:0 HDMI2.0 modes, who reports a clock > max_tmds_clock.
