[PATCH v2 4/6] ARM: mm: Rename PGD helpers

[Kevin Brodsky]

Generic implementations of __pgd_alloc and __pgd_free are about to
be introduced. Rename the macros in arch/arm/mm/pgd.c to avoid
clashes. While we're at it, also pass down the mm as argument to
those helpers, as it will be needed to call the generic
__pgd_{alloc,free}.
