powerpc/pseries: Fix VPHN build errors on non-SMP systems
The header asm/hvcall.h was previously included indirectly via smp.h. On non-SMP systems, however, these declarations are excluded and the build breaks. This is easily fixed by including asm/hvcall.h directly. The VPHN feature is only meaningful on NUMA systems that implement the SPLPAR option, so exclude the VPHN code on systems without SPLPAR enabled. Also, expose unmap_cpu_from_node() on systems with SPLPAR enabled, even if CONFIG_HOTPLUG_CPU is disabled. Lastly, map_cpu_to_node() is now needed by VPHN to manipulate the node masks after boot time, so remove the __cpuinit annotation to fix a section mismatch.
