This will serve to provide qdss driver apis that expose the qdss
driver services to the qdss clients. Qdss clients are expected to
include this header file.
This header file will also provide access to apis implemented
in jtag.c that are responsible for debug and etm register save and
restore.

Some users of SCM need to detect features and also detect if
those features have certain versions available. Most notably the
jtag save restore code needs to detect if the secure environment
supports save and restore of jtag state so that it can skip doing
its own save and restore.
Add this API so that the code can work with either version of the
secure code.

As the timer generates interrupts on a different PPI depending
