ARM ETM/ETB/trace: help/usage updates
Provide helptext which was sometimes missing; update some of it
to be more accurate.
Usage syntax messages have the same EBNF as the User's Guide;
no angle brackets in either place.
Don't use "&function"; functions are like arrays, their address
is their name. Shrink some overlong lines, remove some empties.
