Log Message:
xhci(4): Avoid holding bus lock across usb_delay_ms.

We may still need a mechanism to serialize access to the portsc
registers between xhci_roothub_ctrl and xhci_suspend/resume, but the
bus lock is no longer that, and holding the bus lock across
usb_delay_ms may lead to deadlock by blocking the softints that wake
usb_delay_ms.
