soc/intel: Fix regression with hidden PCI devices
Fix regression with commit
903b40a soc/intel: Replace uses of dev_find_slot()
Platforms where FSP hides PCI devices before enumeration
may halt with error message 'PCI: dev is NULL!'.
The workaround here is to print an error message revealing
the faulty source code function and revert to old behaviour
of dev_find_slot().
