Subject: [PATCH 01/12] spmi: make spmi_bus_type const

From: "Ricardo B. Marliere" <ricardo@...liere.net>

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