net: pch_gbe: Propagate error from devm_gpio_request_one()

Browse Source 
[ Upstream commit 9e3617a7b84512bf96c04f9cf82d1a7257d33794 ]

If GPIO controller is not available yet we need to defer
the probe of GBE until provider will become available.

While here, drop GPIOF_EXPORT because it's deprecated and
may not be available.
