Balbir Singh 4077960e2a memory controller: make memory resource control aware of boot options 
A boot option for the memory controller was discussed on lkml.  It is a good
idea to add it, since it saves memory for people who want to turn off the
memory controller.

By default the option is on for the following two reasons:

1. It provides compatibility with the current scheme where the memory
   controller turns on if the config option is enabled
2. It allows for wider testing of the memory controller, once the config
   option is enabled

We still allow the create, destroy callbacks to succeed, since they are not
aware of boot options.  We do not populate the directory will memory resource
controller specific files.
