usb: chipidea: usbmisc: fix a potential race condition

This fixes a potential race condition where the ci13xxx_imx glue code
could be fast enough to call one of the usbmisc_ops before he got a
valid value on the static usbmisc pointer. To fix that we first set
usbmisc, then call usbmisc_set_ops().
