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.

Similar to what was done on etm3x, splitting driver structure
etmv4_drvdata in two. One half is concerned with the HW
characteristics that are generally static in nature. The other
half deals with user configuration and will change from one
trace session to another.
No gain/loss of functionality is incurred from this patch.

Adding new sysFS management interface to query the configuration
and the traceid registers. Both are required to convey information
to the perf cmd line tools when using ETMv4 tracers as PMU.

As with the etm3x driver, sysFS entries are big enough to justify
their own file. As such moving all sysFS related declarations to
a dedicated location.
