[PATCH] pci: move pcie_pme_root_status_cleanup into SUSPEND section

[Arnd Bergmann]

The power management code in pci-driver.c is a maze of #ifdefs, and
the newly added pcie_pme_root_status_cleanup function ended up in the
wrong one of them, causing a harmless warning in some configurations:

drivers/pci/pci-driver.c:527:13: error: 'pcie_pme_root_status_cleanup' defined 
but not used [-Werror=unused-function]
 static void pcie_pme_root_status_cleanup(struct pci_dev *pci_dev)
             ^~~~~~~~~~~~~~~~~~~~~~~~~~~~

This moves the definition into the correct #ifdef section.

Fixes: 6c4dfc1389e1 ("PCI/PM: Clear PCIe PME Status bit in core, not PCIe port 
driver")
