[PATCH] ssb: make ssb_bustype const

[Ricardo B. Marliere]

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

Greg, I saw your Reviewed-by email 7 times. Not sure if the problem is
on my end or your end but wanted to make sure you are aware of it.
