trace: Eliminate use of TARGET_FMT_plx

hw/tpm/trace-events uses TARGET_FMT_plx formats with uint64_t
arguments.  That's wrong, TARGET_FMT_plx takes hwaddr.  Since hwaddr
happens to be uint64_t, it works anyway.  Messed up in commit
ec42749, v2.12.0.  Clean up by replacing TARGET_FMT_plx with its
macro expansion.

scripts/tracetool/format/log_stap.py (commit 62dd104, v4.0.0) has
a special case for TARGET_FMT_plx.  Delete it.
