powerpc/mm: Standardise __ptep_test_and_clear_young() params between PPC32 and PPC64
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.
