drm: remove i830 driver
This driver is one of the last users of the big kernel lock, which is going away. All the hardware supported by this driver also works with the newer i915 driver, and recent X.org releases only work with that driver anyway. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Cc: Chris Wilson <chris@chris-wilson.co.uk> Cc: dri-devel@lists.freedesktop.org Signed-off-by: Dave Airlie <airlied@redhat.com>
