Ah -- gunyah_rsc_mgr.ko has symbol dependency on gunyah-msgq.ko.
gunyah-msgq.ko has symbol dependency on gunyah.ko. gunyah.ko doesn't
have any probe and does all its work on module_init.

In order to merge gunyah.c with resource manager, I would need to
incorporate message queue mailbox into resource manager. IMO, this
rapidly moves towards a mega-module which was discouraged previously.

Thanks,
Elliot
