PCI ACPI: Added a function to register _OSC with only PCIe devices.
The function pci_osc_support_set() traverses every root bridge when
checking for _OSC support for a capability. It quits as soon as it finds a
device/bridge that doesn't support the requested capability. This won't
work for systems that have mixed PCI and PCIe bridges when checking for
PCIe features. I split this function into two -- pci_osc_support_set() and
pcie_osc_support_set(). The latter is used when only PCIe devices should be
traversed.
