Tom Rini dc2d27ae72 arm: samsung: Remove dead LCD code
Since bb5930d5c9 ("exynos: video: Convert several boards to driver
model for video") there have been no callers of any of the exynos_lcd_*
family of functions.  Remove these from the boards, and then remove
unused logo and related code as well.
