The way X86_TSC works and the fact that Xen itself won't work on
systems without TSC (really any systems pre-dating i686) makes it
unnecessary for XEN to depend on it.
Similarly, X86_CMPXCHG isn't needed here either as Xen for the above
reason guarantees its availability.
This allows the option to be available when selecting M386, M486, or
M586.
