While some VF/PF relay actions must be handled on the GT level, like query for runtime registers, it was clarified by the arch team that initial version negotiation can be done by the VF just once, by using any available GuC/GT. Move handling of the VF/PF ABI version negotiation on the PF side from the GT level functions to the device level functions.
