Subject: [PATCH] drm/i915: Add double_wide readout and checking
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

Read the double wide pipe information from hardware in
i9xx_get_pipe_config(), and check it in intel_pipe_config_compare()

For gen4+ double_wide is always false so the comparison can be done
on all platforms.
