We need to multiply the hdmi port dotclock by 1.5x since it's not really a dotclock, but the 10/8 encoding bitclock divided by 10. Also add correct limit checks for the dotclock and reject modes which don't fit. HDMI 1.4 would allow more, but our hw doesn't support that unfortunately :( Somehow I suspect 12bpc hdmi output never really worked - we really need an i-g-t testcase to check all the different pixel modes and outputs. v2: Fixup the adjusted port clock handling - we need to make sure that the fdi link code still gets the real pixelclock. v3: g4x/vlv don't support 12bpc hdmi output so drop the bogus comment.
