[Intel-gfx] [REVERT] - drm/i915: Removing TV Out modes

[Robert Lowery]

Further to my previous post regarding getting TV Out working on recent
kernels, I see a recent check in to the mainline kernel source removed
support for 576p TV output which I use.

Could someone please revert
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=55a6713b3f30a5024056027e9dbf03ac8f13bfc9
or at least reinstate the 576p mode that I use.

I think 480p at 59.94Hz is also a valid mode (though I don't use it) and
should be left in and perhaps be renamed to just 480p since there is now
no need to differentiate frequencies.

Something like this?
