drm/exynos: fix fimd pixel format setting
This patch fixes wrong pixel format setting. A pixel format is decided according to bpp and depth, or user-requested format but fimd driver considered only bpp value to decide a proper pixel format. So this patch makes a proper pixel format to be set according to drm_framebuffer's pixel_format which is set by addfb with bpp and depth, or addfb2 with user-requested format.
