Tertiary match group was added to CMN-650 and newer implementations.
This patchset makes the parameters model specific to support properly
various models. Also, wp_config registers and filter groups numbers are
decoupled to enable the new match group.

v2:
	* Use bitmap to track which WPs/DTMs are used by the event
	* Dropped model specific parameters
	* Addressed other Robin's comments regarding to sysfs, sanity-check
	  of wp arguments, and wp_combine check

v1:

Ilkka Koskinen (2):
  perf/arm-cmn: Decouple wp_config registers from filter group number
  perf/arm-cmn: Enable support for tertiary match group
