Thomas Ballasi c336fae2c5 usb: chipidea: imx: avoid unnecessary probe defer 
The changes brought by commit 73de934401 have been inadvertidly
removed, causing ci_hdrc_imx's probe to be loaded before usbmisc_imx's,
despite ci_hdrc_imx needing usbmisc_imx.

This condition may cause unexpected behaviors, especially when the
ChipIdea node is being referred to under /sys/class/udc/:

$ ls -l /sys/class/udc/
$

when it should show as the following:

$ ls -l /sys/class/udc/
ci_hdrc.0 -> ../../devices/[...]/ci_hdrc.0/udc/ci_hdrc.0

Some userspace tools may depend on this feature[1].
