We have a number of drivers that can be used with and without device trees. On AT91, some non-OF enabled configurations run from on-chip SRAM, which is limited to few tens of kilobytes in size. We need to be very size-concious there and having deep_probe_is_supported() as static inline helper evaluating to false when unused makes it easy to discard code that is not needed for the non-OF case.
