stable inclusion from linux-4.19.198 commit 4de95ea6e064f0e519e4899d14705406e105f1bd
--------------------------------
[ 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.
