cpus hw target: Use warn_report() & friends to report warnings

Calling error_report() in a function that takes an Error ** argument
is suspicious.  Convert a few that are actually warnings to
warn_report().

While there, split a warning consisting of multiple sentences to
conform to conventions spelled out in warn_report()'s contract.
