ssbi: Allow compilation as a module

Browse Source 
The ssbi driver's read/write entry points are protected with wrappers
in the case when the driver isn't enabled.  These wrappers don't make
any sense, since a client of the SSBI bus won't work without it.  Make
these just regular functions, so that the SSBI driver can be built as
a module.
