[PATCH] drm/gma500: Remove generic DRM drivers in probe function

[Thomas Zimmermann <tzimmermann@suse.de>]

Gma500 currently removes generic fbdev drivers, but ignores
generic DRM drivers. Use aperture helpers to remove all generic
graphics drivers before loading gma500. Makes gma500 compatible
with simpledrm.
