drm/exynos: update fb_info via only one function
This patch moves codes to update fb_info into exynos_drm_fbdev_update(), so fb_info is updated via only one function. Signed-off-by: Joonyoung Shim <jy0922.shim@samsung.com> Reviewed-by: Gustavo Padovan <gustavo.padovan@collabora.co.uk> Signed-off-by: Inki Dae <inki.dae@samsung.com>
