x86/xen: make CONFIG_XEN depend on CONFIG_X86_LOCAL_APIC

Since commit feb44f1 (x86/xen: Provide a "Xen PV" APIC driver to support >255 VCPUs) Xen guests need a full APIC driver and thus should depend on X86_LOCAL_APIC. This fixes an i386 build failure with !SMP && !CONFIG_X86_UP_APIC by disabling Xen support in this configuration. Users needing Xen support in a non-SMP i386 kernel will need to enable CONFIG_X86_UP_APIC. Signed-off-by: David Vrabel <[email protected]> Cc: <[email protected]>
