The node type field is an enum type, so print it as a 32-bit quantity
rather than as an unsigned short.

Ensure that the 'irq' field of 'struct arm_cmn_dtc' is a signed int
so that it can be compared '< 0'.

Initial driver for PMU event counting on the Arm CMN-600 interconnect.
CMN sports an obnoxiously complex distributed PMU system as part of
its debug and trace features, which can do all manner of things like
sampling, cross-triggering and generating CoreSight trace. This driver
covers the PMU functionality, plus the relevant aspects of watchpoints
for simply counting matching flits.
