powerpc: Remove old dump_task_* functions
Since Roland's ptrace cleanup starting with commit f65255e8d51ecbc6c9eef20d39e0377d19b658ca ("[POWERPC] Use user_regset accessors for FP regs"), the dump_task_* functions are no longer being used. Signed-off-by: Michael Neuling <mikey@neuling.org> Signed-off-by: Paul Mackerras <paulus@samba.org>
