I think you can solve this in another way.

As a start, I would suggest to change above to CONFIG_PM_SLEEP

Remove the use of DEV_PM_OPS define. Instead use below macro and
outside #ifdef CONFIG_PM_SLEEP.

"static SIMPLE_DEV_PM_OPS(xhci_plat_pm_ops, xhci_plat_suspend,
xhci_plat_resume)"

That should do the trick I believe, without the need for changing the
existing SET_SYSTEM_SLEEP_PM_OPS macro in patch1.

Kind regards
