PCI: dwc: Add dw_pcie_link_set_max_link_width()
This is a preparation before adding the Max-Link-width capability
setup which would in its turn complete the max-link-width setup
procedure defined by Synopsys in the HW-manual.
Seeing there is a max-link-speed setup method defined in the DW PCIe
core driver it would be good to have a similar function for the link
width setup.
That's why we need to define a dedicated function first from already
implemented but incomplete link-width setting up code.
