ftrace: disable dynamic ftrace for all archs that use daemon

The ftrace daemon is complex and can cause nasty races if something goes
wrong. Since it affects all of the kernel, this patch disables dynamic
ftrace from any arch that depends on the daemon. Until the archs are
ported over to the new MCOUNT_RECORD method, I am disabling dynamic
ftrace from them.

Note: I am leaving in the arch/<arch>/kernel/ftrace.c code alone since
that can be used when the arch is ported to MCOUNT_RECORD. To port
the arch to MCOUNT_RECORD, the scripts/recordmcount.pl needs to be
updated. I will make that easier to do for 2.6.29. For 28, we will keep
the archs disabled.
