usb: chipidea: imx: properly check for usbmisc
If usbmisc hasn't probed yet, defer the probe. It's not enough to check if the platform device for the OF node of the usbmisc has been registered, but it also needs to have been probed already before we can call imx_usbmisc_init(). This can happen if the order in which devices are probed change due to async probing or on-demand probing of dependencies. Signed-off-by: Tomeu Vizoso <tomeu.vizoso@collabora.com>
