Even though I think it is nice to be able to completely disable the
mapcache from a compile time option, in practice we don't use it and we
don't even have it in qemu-xen.
Also I am pretty sure that disabling the mapcache at the moment would
prevent qemu from working on xen completely.
So I think it is OK to remove the option.
