[PATCH] USB: EHCI updates mostly whitespace cleanups

Browse source 
This cleans up the recent updates to EHCI PCI support:

  - Gets rid of checks for "is this a PCI device", they're no
    longer needed since this is now all PCI-only code.

  - Reduce log spamming:  MWI is only interesting in the atypical
    case that it can actually be used.

  - Whitespace cleanup, as appropriate for a new file with no
    other pending patches.

So other than that minor logging change, no functional updates.
