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.
