[PATCH 6/6] ARM: provide individual is_translation_fault() and is_permission_fault()

["Russell King (Oracle)" <rmk+kernel@armlinux.org.uk>]

Provide individual LPAE and non-LPAE definitions for both these
functions, rather than having ifdefs inside the function body. This
places the functions closer to their associated definitions.
