This patch changes the order in which the driver waits for the
target to become ready and the service connect of the HTC
control service.
The HTC control service is connected before the driver starts
waiting for the HTC ready control message.
The reason for this is that the HTC ready control message is
transmitted on EP 0 and that sdio/mbox based systems will ignore
messages received on unconnected endpoints.
