drm/meson: vclk: fix calculation of 59.94 fractional rates
[ Upstream commit bfbc68e4d8695497f858a45a142665e22a512ea3 ]
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.
