This works for the case where we do want to create a TLB entry, because we know the common TLB code only creates entries of the TARGET_PAGE_SIZE and asking for a size larger than that only means that invalidations invalidate the whole larger area. However, if lg_page_size is smaller than TARGET_PAGE_SIZE this effectively means "don't create a TLB entry"; in this case if either S1 or S2 said "this covers less than a page and can't go in a TLB" then the final result also should be marked that way. Set the resulting page size to 0 if either stage asked for a less-than-a-page entry, and expand the comment to explain what's going on. This has no effect for VMSA because currently the VMSA lookup always returns results that cover at least TARGET_PAGE_SIZE; however when we add v8R support it will reuse this code path, and for v8R the S1 and S2 results can be smaller than TARGET_PAGE_SIZE.

Rather than converting the MAIR format to the format used for VMSA stage 2 (bits [5:2] of a VMSA stage 2 descriptor) and then converting back to do the attribute combination, allow combined_attrs_nofwb() to accept s2 attributes that are already in the MAIR format. We move the assert() to combined_attrs_fwb(), because that function really does require a VMSA stage 2 attribute format.
