[PATCH v3 20/45] powerpc/mm: Standardise __ptep_test_and_clear_young() params between PPC32 and PPC64

[Christophe Leroy]

On PPC32, __ptep_test_and_clear_young() takes the mm->context.id

In preparation of standardising pte_update() params between PPC32 and
PPC64, __ptep_test_and_clear_young() need mm instead of mm->context.id

Replace context param by mm.
