Modified Files:
        src/sys/dev/usb: xhci.c xhcireg.h

Log Message:
enable code to only trigger usb processing when EINT is set, to
avoid misinterpreting shared interrupt for another device

when clearing USBSTS, actually preserve the bits which spec requires to
preserve, and actually clear bit 1, which should be actually always
cleared to zero by spec

also #ifdef XHCI_DEBUG some unnecessary register reads

this should finally resolve PR kern/53066 also for Martin
