[PATCH v5 1/4] PCI: No need to set d3cold_allowed to PCIe ports

[Mika Westerberg <mika.westerberg@linux.intel.com>]

The Linux PCI core skips PCI bridges and PCIe ports when 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.
