perf session: Dump PERF_RECORD_TIME_CONV event
Now perf tool uses the common stub function process_event_op2_stub() for
dumping TIME_CONV event, thus it doesn't output the clock parameters
contained in the event.
This patch adds the callback function for dumping the hardware clock
parameters in TIME_CONV event.
Before:
# perf report -D
0x978 [0x38]: event: 79
.
. ... raw event: size 56 bytes
. 0000: 4f 00 00 00 00 00 38 00 15 00 00 00 00 00 00 00 O.....8.........
