Subject: [PATCH] PCI: generic: stop hiding pci_host_common_probe declaration

When pci_host_common_probe() was moved into a separate module, the #ifdef around
the declaration was left in the header file, which can lead to build errors in
some configurations:

drivers/pci/host/pci-thunder-pem.c: In function 'thunder_pem_probe':
drivers/pci/host/pci-thunder-pem.c:412:9: error: implicit declaration of function 'pci_host_common_probe';did you mean 'pci_host_bridge_priv'? [-Werror=implicit-function-declaration]

The ifdef serves no real purpose anyway, so we can just remove it.

Fixes: 4e64dbe226e7 ("PCI: generic: Expose pci_host_common_probe() for use by other drivers")
