If CONFIG_PM_SLEEP is not set, SET_SYSTEM_SLEEP_PM_OPS() is expanded to
empty macro and there is no reference to rcar_pcie_resume(), hence the
following warning is generated:
drivers/pci/controller/pcie-rcar.c:1253:12: warning: ‘rcar_pcie_resume’ defined but not used [-Wunused-function]
1253 | static int rcar_pcie_resume(struct device *dev)
| ^~~~~~~~~~~~~~~~
Fix this by marking this function as __maybe_unused , just like in
commit 226e6b866d74 ("gpio: pch: Convert to dev_pm_ops")

I hope Lorenzo will squash this into the original commit. I don't
think it adds anything useful to keep it as a separate commit.

Fine by me, that's also why I added these notes, so it's obvious it's
based off the same branch where the previous patch is already.
