[PATCH RFC v3 01/21] ARM: mm: make nommu pgd_t a scalar

[Yeoreum Yun]

From: "David Hildenbrand (Arm)" <david at kernel.org>

As pgd_t is returned  from a function, like pgdp_get(). pgd_t shouldn't be
an array.

There is no need to match the actual arm page tables, because with nommu
there are no page tables. It's all just in place to make the compiler
happy. Making it a scalar will make the compiler happy.

So let's just use an u32.
