PCI: Don't clear d3cold_allowed for PCIe ports
The PCI core skips bridges and ports when the system is suspended. The PCI
core checks return value of pci_has_subordinate() in pci_pm_suspend_noirq()
to skip all devices where it is non-zero (which means PCI bridges and PCIe
ports).
Since PCIe ports are never suspended in the first place, there is no need
to set d3cold_allowed for them.
