From: Luca Coelho <luciano.coelho@intel.com>

Now that we don't have dynamically changing domains anymore, we can
simply skip all the TLVs with domains that are not enabled.  To do so,
remove the checks from the functions that handle the TLVs when a
timepoint is reached to the top allocation function.
