[PATCH 05/39] mm: make map_kernel_pages_[prepare,complete] internal and unexported

[Lorenzo Stoakes (ARM)]

There's no reason to export the symbols for these functions which are only
called from internal mm logic, additionally there's no reason for them to
be declared in mm.h.

This patch therefore removes the exports and moves the declarations to
mm/internal.h.

No functional change intended.
