mixer_check_mode drops Exynos5 display modes

Hi Sean,

While looking at the following commit I noticed something:

commit f041b257a8997c8472a1013e9f252c3e2a1d879e Author: Sean Paul seanpaul@chromium.org Date: Thu Jan 30 16:19:15 2014 -0500

drm/exynos: Remove exynos_drm_hdmi shim

This commit changes how mixer_check_mode() is used. It used to just exclude certain modes on old mixer versions, but now it seems to be called unconditionally, for all mixer versions. I guess the effect here is that some modes on exynos5 setups are dropped whereas they weren't before. Is that intentional?

Thanks Daniel
