staging: fsl-mc: Refactored fsl_mc_object_allocator driver init/exit
The fsl_mc_allocator driver does not need to be its own module
as it is tightly integrated into the MC bus main driver. It is really
just a sub-component of the MC bus driver. By not making fsl_mc_allocator
its own module, we can have more control of when its initialization happens
and we want it to happen before any driver that depends on the MC bus
driver gets initialized.
