   - usb3-lpm-capable: determines if platform is USB3 LPM capable
   - quirk-broken-port-ped: set if the controller has broken port disable mechanism
   - imod-interval-ns: default interrupt moderation interval is 5000ns

   - phys : see usb-hcd.txt in the current directory
This should be implied by the HCI or phy compatible string (depending 
on who exactly needs the quirky behavior).
