Unbinding and re-binding the root DPRC fails with:

  sysfs: cannot create duplicate filename '/dev/char/10:256'
    misc_register / fsl_mc_uapi_create_device_file /
    dprc_setup / dprc_probe

I have no comments on the actual code changes, only that the patch would
benefit from a more complete message.

Please explain a bit when the issue happens (only when the fsl-mc bus
probe is not defered - meaning no smmu). Also mention in the commit
message as well that you are moving the dprc and allocator drivers
registration at the subsys_initcall_sync stage while the misc_init() is
called at subsys_initcall.
