CONFIG_NET_VENDOR_FREESCALE should hide/show all Freescale drivers.

Once you show all Freescale drivers, there should be an option to
enable each individual driver.

Does the ENETC_VF driver depend on the ENETC driver? If so, when
CONFIG_FSL_ENETC is enabled, the CONFIG_FSL_ENETC_VF should be
unhidden.
