stable inclusion from stable-5.10.50 commit 2d487941ee598e94155d0e70c2a49c4554743f3c bugzilla: 174522 https://gitee.com/openeuler/kernel/issues/I4DNFY
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=...
--------------------------------
[ 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.
