lib/trace: Remove TRACE support

Looks like the option is generally not compatible with
garbage collections.

Nothing gets inlined, for example is_smp_boot() no longer
evaluates to constant false and thus the symbols from
secondary.S would need to be present for the build to pass
even if we set SMP=n.

Also the addresses of relocatable ramstage are currently
not normalised on the logs, so util/genprof would be unable
dress those.
