Install 10.0-RC3 on MacBookPro Late 2013

[Huang Wen Hui]

Hans,

This wild guess do NOT works.
I binary sect xhci.c in SVN, found that *r245732
*<http://svnweb.freebsd.org/base?view=revision&revision=245732>*
introduce the bug.*
 <http://svnweb.freebsd.org/base?view=revision&revision=245732>
revert to r345731 fixed this USB problem in 9.2R

I also copy xhci_interrupt(struct xhci_softc *sc) from 9.1R to CURRENT,
CURRENT also works!

Cheers,
Huang Wen Hui.
