    Various minor EHCI updates
    
       * Dump some more info in the debug dumps, notably the product
         description (e.g. chip vendor), BIOS handhake flags, and
         debug port status (when it's not managed by the HCD).
    
       * Minor updates to the BIOS handoff code:  always flag the HCD
         as owned by Linux (in case BIOS doesn't grab it "early"),
         and on the buggy-BIOS path always match the "early handoff"
         code and forcibly disable SMI IRQs.
    
       * For the disabled 64bit DMA support, there's now a constant
         to use for the mask; use it.
