coresight: moving coresight_simple_func() to header file

Browse source 
Macro "coresight_simple_func()" can be used by several drivers.
As such making the structure type generic and moving to a
globally available header file.  That way individual drivers
can use the functionality by simply specifying the structure
they need to work with.
