drm/rockchip: inno_hdmi: Add basic mode validation


As per TRM this controller supports pixelclocks starting from 25 MHz. The
maximum supported pixelclocks are defined by the phy configurations we
have. Also it can't support modes that require doubled clocks. If the
variant has a phy reference clock we can additionally validate against VESA
DMT'srecommendations.
