Justin Hammond c94fbeebcb drivers/usbhost: Stop an xHCI controller only when it is running.
xhci_ctrl_halt() wrote USBCMD zero unconditionally and then waited for
HCH.  A controller that was never started is already halted, so the wait
ran to its full length, and clearing the whole register also dropped
INTE and HSEE.

Test HCH first, clear only R/S when it is set, bound the wait with
XHCI_HALT_TIMEOUT_MS, and report USBCMD and USBSTS on failure.
