This series is part of an effort to cleanup the users of the driver
core, as can be seen in many recent patches authored by Greg across the
tree (e.g. [1]). Specifically, this series is part of the task of
splitting one of his TODOs [2].

Now that the driver core can properly handle constant struct bus_type,
move the mmc_rpmb_bus_type variable to be a constant structure as well,
placing it into read-only memory which can not be modified at runtime.
