[PATCH] nvmem: make nvmem_bus_type constant

[Greg Kroah-Hartman <gregkh@linuxfoundation.org>]

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