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.
