drm/xe/vf: Don't claim support for firmware late-bind if VF

In general, the VFs can't load firmwares so attempt to initialize
the firmware late-bind component leads to errors like:

 [] xe 0000:03:00.1: [drm] *ERROR* Late bind component not bound

Fixes: 918bd789d62e ("drm/xe/xe_late_bind_fw: Introduce xe_late_bind_fw")
