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.

Adding a new mode to source API enable() in order to
distinguish where the request comes from. That way it is
possible to perform different operations based on where
the request was issued from.
The ETM4x driver is also modified to keep in sync with the
new interface.

Splitting "etm_drvdata" in two sections, one for the HW specific
data and another for user configuration.
That way it is easier to manipulate and zero out the configuration
data when more than one concurrent tracing session configuration
is active.
Also taking care of up-lifting all the code affected by this new
arrangement. No loss or gain of functionality (other than what is
mentioned above) is introduced by this patch.

SysFS entries are big enough to justify their own file.
As such moving all sysFS related declarations to a dedicated
location.
