powerpc/8xx: DEBUG_PAGEALLOC doesn't require an ITLB miss exception handler
Since commit e611939fc8ec ("powerpc/mm: Ensure change_page_attr()
doesn't invalidate pinned TLBs"), pinned TLBs are not anymore
invalidated by __kernel_map_pages() when CONFIG_DEBUG_PAGEALLOC is
selected.
Remove the dependency on CONFIG_DEBUG_PAGEALLOC.
