[PATCH RESEND] xfree86: Find primary entity when bus types are nominally different

As of server 1.13, systems with DRM and Udev will have BUS_PLATFORM as
their primary bus type. However, drivers not implementing a
platformProbe function will still create entities of type BUS_PCI. We
need to account for this when checking for the primary entity.
