PCI: layerscape: Add workaround for lost link capabilities during reset
The endpoint controller loses the Maximum Link Width and Supported Link Speed
value from the Link Capabilities Register - initially configured by the Reset
Configuration Word (RCW) - during a link-down or hot reset event.
Address this issue in the endpoint event handler.
