ftrace: remove address of function names

PowerPC is very fragile when it comes to use of function names
and function addresses.  ftrace needs to either use all function
addresses or function names (i.e. my_func as suppose to &my_func).

This patch chooses to use the names and not the addresses, and
makes ftrace consistent.
