drivers/efi/variable_store: Select necessary UDK binding as needed

Browse source 
DRIVERS_EFI_VARIABLE_STORE requires some Intel vendorcode headers which
are selected by default on FSP 2.x platforms, but not by earlier ones.
Select the oldest UDK binding for non-FSP 2.x boards, so that the
required headers are available, rather than depending on UDK_BASE
and requiring those boards to manually select the binding.

TEST=build samsung/stumpy with EFI variable store support, without
manually selecting UDK_2017_BINDING at the mainboard level.
