can: flexcan: Deferred on Regulator return EPROBE_DEFER
Return EPROBE_DEFER if Regulator returns EPROBE_DEFER
If the Flexcan driver is built into kernel and a regulator is used to
enable the CAN transceiver, the Flexcan driver may not use the regulator.
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.
