Fix ARM profiling/instrumentation configuration
Commit 09cadedbdc01f1a4bea1f427d4fb4642eaa19da9 ("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.
