When initializing the Flexcan device with a regulator defined in the device tree, but not initialized, the regulator subsystem returns EPROBE_DEFER, hence the Flexcan init fails. The solution for this is to return EPROBE_DEFER if regulator is not initialized and wait until the regulator is initialized.
