xf86drm: implement drmParsePciBusInfo for OpenBSD
Implement drmParsePciBusInfo for OpenBSD by using the new DRM_IOCTL_GET_PCIINFO ioctl. v2: use drmGetMinorType to get node type instead of always using DRM_NODE_PRIMARY. Signed-off-by: Jonathan Gray <jsg@jsg.id.au> Reviewed-by: Emil Velikov <emil.l.velikov@gmail.com>
