Exynos hdmi driver is using drm_display_mode for setting timing values
for a supported resolution. Conversion to fb_videomode and then comparing
with the mixer/hdmi/phy limits is not required. Instead, drm_display_mode
fields cane be directly compared.
v2:
1) Removed convert_to_video_timing().
2) Corrected DRM_DEBUG_KMS to print the resolution properly.
