soc: qcom: wcnss_ctrl: Make wcnss_ctrl parent the other components
We need the signal from wcnss_ctrl indicating that the firmware is up and running before we can communicate with the other components of the chip. So make these other components children of the wcnss_ctrl device, so they can be probed in order. The process seems to take between 1/2-5 seconds, so this is done in a worker, instead of holding up the probe.
