media: qcom: camss: vfe: fix PIX subdev naming on VFE lite

VFE lite hardware does not provide a functional PIX path, but after
the per sub-device type resource changes the PIX subdev name is still
assigned unconditionally.

Only assign the PIX subdev name on non-lite VFE variants to avoid
exposing a misleading device name.
