Commit 09cadedbdc ("Combine
instrumentation menus in kernel/Kconfig.instrumentation") broke ARM
profiling support, since ARM has some extra Kconfig options and doesn't
just use the common OPROFILE/KPROBES config options.
Rather than just revert the thing outright, or add ARM-specific
knowledge to the generic Kconfig.instrumentation file (where the only
and whole point was to be generic, not too architecture-specific), this
just makes ARM not use the generic version, since it doesn't suit it.
So create an arm-specific version of Kconfig.instrumentation instead,
and use that.
