    broadwell: Correct XHCI offset for USB 3.0 ports
    
    Looks like Intel has added two more USB 2.0 ports from LynxPoint to
    Broadwell, which shifted the port offsets of the USB 3.0 ports behind
    them. The USB 2.0 ports are now 0x480 to 0x520 and the 3.0 ones 0x530 to
    0x560 (at least according to what my kernel seems to think). The offset
    of the first USB 3.0 port is hardcoded and seems to have been copied
    over without accounting for this, meaning when we try to operate on all
    USB 3.0 ports we actually operate on the last two 2.0 and the first two
    3.0 ports instead.
    
    This patch should fix the bug for now. In the future, we might want to
    consider dynamically detecting port locations through the Protocol
    Capability structures at the end of the XHCI register set instead.
