Christian Hewitt bfbc68e4d8 drm/meson: vclk: fix calculation of 59.94 fractional rates 
Playing 4K media with 59.94 fractional rate (typically VP9) causes the screen to lose
sync with the following error reported in the system log:

[   89.610280] Fatal Error, invalid HDMI vclk freq 593406

Modetest shows the following:

3840x2160 59.94 3840 4016 4104 4400 2160 2168 2178 2250 593407 flags: xxxx, xxxx,
drm calculated value -------------------------------------^

Change the fractional rate calculation to stop DIV_ROUND_CLOSEST rounding down which
results in vclk freq failing to match correctly.
