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.

Cant this GPIO changes go to pinmux file?
No it's smdk5250 specific. Other board has different GPIOs.
Thank you,
