[PATCH v2 08/11] common: deep-probe: don't build without CONFIG_OFDEVICE

[Ahmad Fatoum <a.fatoum@pengutronix.de>]

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.
