Imo "depends on" on prompt-less, default-off options are at best unhelpful
in the common case. (Aiui it can be helpful when "imply" is used instead of
"select".) Hence I think this dependency wants dropping right in this patch,
justified further by ...

... the XEN dependency being in both of the options selecting XEN_PVHVM and,
as per Jürgen's patch, X86_LOCAL_APIC being redundant anyway.
