[PATCH] drm/i915: Fix module initialisation, v2.

[Maarten Lankhorst <maarten.lankhorst@linux.intel.com>]

Set DRIVER_MODESET and DRIVER_ATOMIC by default. The driver is fully atomic.
Remove the legacy suspend/resume, to fix a warning introduced by:

"drm: WARN_ON if a modeset driver uses legacy suspend/resume helpers"

and removing the .get_vblank_timestamp reset to NULL. It's a noop without UMS.
