[PATCH v2 15/15] staging/mgakms: Update matroxfb driver code for DRM

[Thomas Zimmermann <tzimmermann@suse.de>]

With the update, all driver code coming from matroxfb is build
unconditionally. The driver registers itself with the mgakms driver,
instead of the fbdev core.

Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de>
