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.
changes in V2: -- Move LCD GPIO confiration from exynos common file to board file. changes in V3: -- Remove explicit call for cfg_lcd_gpio and add it as callback. changes in V4: -- use logo_on = 1 for smdk5250 panel_info structure. changes in V5: -- Move CONFIGS from smdk5250.h to exynos5250-dt.h. -- Added changelog in commit message.
