phy/rockchip: inno-hdmi: round fractal pixclock in rk3328 recalc_rate 



inno_hdmi_phy_rk3328_clk_recalc_rate() is returning a rate not found
in the pre pll config table when the fractal divider is used.
This can prevent proper power_on because a tmdsclock for the new rate
is not found in the pre pll config table.

Fix this by saving and returning a rounded pixel rate that exist
in the pre pll config table.
