PCI: Apply _HPX Link Control settings to all devices with a link
Previously we applied _HPX type 2 record Link Control register settings only to bridges with a subordinate bus. But it's better to apply them to all devices with a link because if the subordinate bus has not been allocated yet, we won't apply settings to the device. Use pcie_cap_has_lnkctl() to determine whether the device has a Link Control register instead of looking at dev->subordinate.
