[PATCH] PCI: dwc: tune down link up messages

[PATCH] PCI: dwc: tune down link up messages

[Lucas Stach]

This function may be called repeatedly while establishing the link,
so printing a message each time a working link is found can add quite
a bit of noise. Tune those messages down to the debug level.
