PCI/ATS: Add pci_pri_supported() to check device or associated PF
For SR-IOV, the PF PRI is shared between the PF and any associated VFs, and
the PRI Capability is allowed for PFs but not for VFs. Searching for the
PRI Capability on a VF always fails, even if its associated PF supports
PRI.
Add pci_pri_supported() to check whether device or its associated PF
supports PRI.
