x86: don't compile vsmp_64 for 32bit
Impact: cleanup that is only needed when CONFIG_X86_VSMP is defined with 64bit also remove dead code about PCI, because CONFIG_X86_VSMP depends on PCI Signed-off-by: Yinghai Lu <yinghai@kernel.org> Cc: Ravikiran Thirumalai <kiran@scalex86.org> Signed-off-by: Ingo Molnar <mingo@elte.hu>
