modesetting: match PCI class 3, any subclass 

If a device is not primary, the PCI device match fails because the
xf86-video-modesetting driver looks specifically for a PCI class match of
0x30000 with a mask of 0xffffff.  This fails to match, for example, a
non-primary Intel VGA device, because it is reported as having a class of
0x38000.

Fix that by ignoring the low 16 bits of the class in the pci_id_match table.
