Christophe Leroy 18d095b255 mm: define __pte_leaf_size() to also take a PMD entry
On powerpc 8xx, when a page is 8M size, the information is in the PMD
entry.  So allow architectures to provide __pte_leaf_size() instead of
pte_leaf_size() and provide the PMD entry to that function.

When __pte_leaf_size() is not defined, define it as a pte_leaf_size() so
that architectures not interested in the PMD arguments are not impacted.

Only define a default pte_leaf_size() when __pte_leaf_size() is not
defined to make sure nobody adds new calls to pte_leaf_size() in the core.
