w1-gpio: handle of_get_gpio() returning -EPROBE_DEFER better
of_get_gpio() might return -EPROBE_DEFER meaning that the driver
providing the gpio isn't ready yet. If that happens for the first gpio
the resulting kernel output without this patch is:
w1-gpio somename: Failed to parse DT
platform somename: Driver w1-gpio requests probe deferral
The first message is misleading and so is suppressed with this patch.
Further if determining the gpio to switch the external pullup yields
-EPROBE_DEFER this error should be passed back to the caller instead of
just continuing without pullup.
