coresight-etm4x: Controls pertaining to the address comparator functions
Adding sysfs entries to control the various mode the address comparator
registers can enact, i.e, start/top, single, and range. Also supplementing
with address comparator types configuration registers access, mandatory
to complete the configuration of the comparator functions.
