[PATCH 2/2] coresight: perf: Use %px for printing pointers

[Leo Yan <leo.yan@arm.com>]

Use "%px" to print a pointer, which is better than casting the pointer
to unsigned long and printing it with the "%lx" specifier.

Note, the printing format will be updated as 64-bit value:

  # cat /sys/devices/cs_etm/sinks/trbe0
  0x000000003744496a

This commit dismisses the following smatch warnings:

  coresight-etm-perf.c:854 etm_perf_sink_name_show() warn: argument 4 to %lx specifier is cast from pointer
  coresight-etm-perf.c:946 etm_perf_cscfg_event_show() warn: argument 4 to %lx specifier is cast from pointer
