powerpc: Add kconfig for muxed smp ipi support
Compile the new smp ipi mux and demux code only if a platform will make use of it. The new config is selected as required. The new cause_ipi smp op is only available conditionally to point out configs where the select is required; this makes setting the op an immediate fail instead of a deferred unresolved symbol at link. This also creates a new config for power surge powermac upgrade support that can be disabled in expert mode but is default on. I also removed the depends / default y on CONFIG_XICS since it is selected by PSERIES. Signed-off-by: Milton Miller <miltonm@bga.com> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
