pcie: Fill PCIESlot link fields to support higher speeds and widths
Make use of the PCIESlot speed and width fields to update link information beyond those configured in pcie_cap_v1_fill(). This is only called for devices supporting a version 2 capability and automatically skips any non-PCIESlot devices. Only devices with increased link values generate any visible config space differences.
