[PULL] 4k enabling

[Damien Lespiau]

Hi Keith,

This series enables 4k HDMI monitors by making X not prune those modes. To do
so, we parse the max TMDS frequency field in the HDMI CEA vendor data block and
check the mode dot clock against it.

Our QA tested it and the ChromeOS guys have merged it in their tree
already and confirmed it does the trick for them. Chris also gave his
r-b tag.

The following changes since commit 2ea973e12f5d954211e1d10085a4c74581b43aca:
