Currently Exynos DRM driver uses DRIVER_NAME ('exynos') name for the core platform device. This is confusing, because it doesn't refer to the function the platform device is performing. This patch renames the platform device to the 'exynos-drm', which matches the convention for naming the platform devices. The name used inside DRM subsystem has not been changed.

A call to pm_runtime_set_active() forces device to be at the active state and skips calling its runtime suspend/resume callbacks. This results in a freeze with a new power domain code based on gen_pd. Fimd driver does all required runtime power management calls, so this pm_runtime_set_active call is buggy. This patch removes it and corrects clock management in probe function (clocks are now enabled by pm_runtime_get_sync() call).

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.
