PATCH 1/1 i386: XEN config option should not depend on X86_TSC/X86_CMPXCHG

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.

Oh, I thought this had already happened. Guess not.

Anyway:
