mm/THP: don't use HPAGE_SHIFT in transparent hugepage code
For architectures like powerpc that support multiple explicit hugepage
sizes, HPAGE_SHIFT indicate the default explicit hugepage shift. For THP
to work the hugepage size should be same as PMD_SIZE. So use PMD_SHIFT
directly. So move the define outside CONFIG_TRANSPARENT_HUGEPAGE #ifdef
because we want to use these defines in generic code with if
(pmd_trans_huge()) conditional.
