video: exynos_fb: Remove callbacks from the driver
Replaced the functionality of callbacks by using a standard set of functions. Instead of implementing and hooking up a callback, put the same code in one of the standard set of functions by overriding it. This patch is tested only on SMDK5250. For Trats and universal_c210 board, it is only compile tested. Signed-off-by: Ajay Kumar <ajaykumar.rs@samsung.com> Signed-off-by: Minkyu Kang <mk7.kang@samsung.com>
