arm64: stacktrace: delete PCS comment

The comment at the top of stacktrace.c isn't all that helpful, as it's
not associated with the code which inspects the frame record, and the
code example isn't representative of common code generation today.

Delete it.

There should be no functional change as a result of this patch.
