[PATCH] bus: moxtet: declare moxtet_bus_type

[Ben Dooks]

The moxtet_bus_type object is exported from the bus
driver, but not declared. Add a declaration for use
and to silence the following warning:

drivers/bus/moxtet.c:105:17: warning: symbol 'moxtet_bus_type' was not declared. Should it be static?
