[PATCH v2 4/5] powerpc64/ftrace: Use the generic version of ftrace_replace_code()

["Naveen N. Rao" <naveen.n.rao@linux.vnet.ibm.com>]

Our implementation matches that of the generic version, which also
handles FTRACE_UPDATE_MODIFY_CALL. So, remove our implementation in
favor of the generic version.
