drm/exynos: Fix fb_videomode <-> drm_mode_modeinfo conversion
The fb_videomode structure stores the front porch and back porch in the
right_margin and left_margin fields respectively. right_margin should
thus be computed with hsync_start - hdisplay, and left_margin with
htotal - hsync_end. The same holds for the vertical direction.

Fix the fb_videomode <-> drm_mode_modeinfo conversion functions
accordingly.
