usbdebug: Halt host controller before resetting it
Resetting an EHCI controller when it is not halted can have
undefined behaviour. This mostly fixes a case where calling
usbdebug_init() twice would fail to reset the USB dongle device
properly.
On amd/persimmon it still requires one extra retry, but at least it
is now possible to have usbdebug enabled for both romstage and
ramstage.
