phy/rockchip: inno-hdmi: round rk3328 recalc frac rate by 1000Hz

Browse Source 
For pixel clock is rounded by 1000Hz, the recalcated clock rate
of fractional frame rate mode, such 59.94/29.97/23.97Hz, is need
to take the 1000Hz rounding. Otherwise it will not find the pre-pll
settings when powering up phy.
