video: exynos_fb: add DT support for FIMD driver
Add function to parse FIMD data from device tree.
The driver still supports non-DT case.
Define panel_info statically in some file if you are not using DT.
If you have defined DT node for FIMD, panel_info will be filled
using the bindings of FIMD DT node.
