The below is printed when printing help information in qemu-system-x86_64
command line, and when CONFIG_TRACE_LOG is enabled:
----------------------------
$ qemu-system-x86_64 -d help
... ...
trace:PATTERN enable trace events
Use "-d trace:help" to get a list of trace events.
----------------------------
However, the options of "trace:PATTERN" are only printed by
"qemu-system-x86_64 -d help", but missing in hmp "help log" command.
Fixes: c84ea00dc2 ("log: add "-d trace:PATTERN"")
