microblaze: define __PAGETABLE_PMD_FOLDED
Microblaze uses custom implementation of PMD folding, but doesn't define __PAGETABLE_PMD_FOLDED, which generic code expects to see. Let's fix it. Defining __PAGETABLE_PMD_FOLDED will drop out unused __pmd_alloc(). It also fixes problems with recently-introduced pmd accounting. Signed-off-by: Kirill A.
