perf_counter: Add dummy perf_counter_print_debug function
Impact: minimize requirements on architectures Currently, an architecture just enabling CONFIG_PERF_COUNTERS but not providing any extra functions will fail to build with perf_counter_print_debug being undefined, since we don't provide an empty dummy definition like we do with the hw_perf_* functions. This provides an empty dummy perf_counter_print_debug() to make it easier for architectures to turn on CONFIG_PERF_COUNTERS. Signed-off-by: Paul Mackerras <paulus@samba.org>
