sim: ppc: clean up various warnings

A random grab bag of minor fixes to enable -Werror for this port.

Cast address vars to long when the format was using %l.
Use %zu with sizeof operations.
Add const to a bunch of strings.
Trim unused variables.
Fix sizeof call to calculate target storage and not the pointer itself.
