Subject: [10/21] drm/i915: Fix TV Out refresh rate.

2.6.32-longterm review patch.  If anyone has any objections, please let me know.

------------------

From: Rodrigo Vivi <rodrigo.vivi@...il.com>

commit 23bd15ec662344dc10e9918fdd0dbc58bc71526d upstream.

TV Out refresh rate was half of the specification for almost all modes.
Due to this reason pixel clock was so low for some modes causing flickering screen.
