s390/mm,hugetlb: don't use pte_val()/pXd_val() as lvalue
Convert pgtable code so pte_val()/pXd_val() aren't used as lvalue
anymore. This allows in later step to convert pte_val()/pXd_val() to
functions, which in turn makes it impossible to use these macros to
modify page table entries like they have been used before.
Therefore a construct like this:
pte_val(*pte) = __pa(addr) | prot;
which would directly write into a page table, isn't possible anymore
with the last step of this series.
