[Nouveau] [PATCH V2] nouveau: Allow 3D accelerators with output ports

[Marek Vasut]

This patch let's cards with PCI class 0x30200 (3D controller) be
operated by the nouveau driver as well. The nv Quadro NVS 450 is
one such card, where the first GPU has PCI class 0x30000 and the
other GPU has PCI class 0x30200. By ignoring the 1 << 9 bit in
the PCI class mask, displays attached to the other GPU can also
be used now.

V2: Use 0x00ff0000 PCI device mask instead of 0x00fffdff to align
    the code with the nouveau kernel driver as requested by Ben.
