coresight: etb10: Add support for CPU-wide trace scenarios
This patch adds support for CPU-wide trace scenarios by making sure that
only the sources monitoring the same process have access to a common sink.
Because the sink is shared between sources, the first source to use the
sink switches it on while the last one does the cleanup. Any attempt to
modify the HW is overlooked for as long as more than one source is using
a sink.
