There are a few places in the kernel where PCI IDs for different Cadence
USB controllers are being used. Besides different naming, they duplicate
each other. Make this all in order by providing common definitions via
PCI IDs database and use in all users. While doing that, rename
definitions as Roger suggested.

Sure, I'll take it, thanks!
