EXYNOS5: Add support for FIMD and DP
Add panel_info structure required by LCD driver and DP panel platdata for SMDK5250. Add GPIO configuration for LCD. Enable FIMD and DP support on SMDK5250. DP Panel size: 2560x1600. We use 16BPP resolution to get LCD console. Signed-off-by: Ajay Kumar <ajaykumar.rs@samsung.com> Acked-by: Simon Glass <sjg@chomium.org> Signed-off-by: Minkyu Kang <mk7.kang@samsung.com>
