I think all, not most DWC drivers should be aligned. Plus the code
here is pretty much the same, so I'm working on moving all this to the
common DWC code. Drivers that need to bring up the link will need to
implement .start_link() (currently only used for EP mode). Most of the
time that is just setting the LTSSM bit which Synopsys thought letting
every vendor do their own register for was a good idea. Sigh.
