PCI: dwc: Rename 'dw_pcie::link_gen' to 'dw_pcie::max_link_speed'
The 'link_gen' field is now holding the maximum supported link speed set
either by the controller driver or by DT through 'max-link-speed'
property.
However, the name 'link_gen' sounds like the negotiated link speed of
the PCIe link.
So rename it to 'max_link_speed' to make it clear that it holds the
maximum supported link speed of the controller.
