    xfree86: Use the TMDS maximum frequency to prune modes

    Instead of only relying on the Range section, we can do better on
    HDMI to find out what is the max dot clock the monitor supports. The
    HDMI CEA vendor block adds a TMDS max freq we can use.

    This makes X not prune 4k resolutions on HDMI.

    v2: Replace X_INFO by X_PROBED in the message that prints the max
        TMDS frequency (Chris Wilson)
