USB: xhci: Wait for host to start running.
commit ed07453fd356025cc25272629e982f5e4607632c upstream.
When the run bit is set in the xHCI command register, it may take a few
microseconds for the host to start running. We cannot ring any doorbells
until the host is actually running, so wait until the status register says
the host is running.
