If the regulator probing is not yet finished this driver
might catch a -EPROBE_DEFER. Returning after this condition
did not remove the created platform device. On a repeated
call to the probe function the of_platform_device_create
fails.
Calling of_platform_device_destroy after EPROBE_DEFER resolves
this bug.
