Christophe Leroy 64d0a506fb powerpc/32: Fix boot failure on non 6xx platforms
Commit d300627c6a ("powerpc/6xx: Handle DABR match before calling
do_page_fault") breaks non 6xx platforms.

  Failed to execute /init (error -14)
  Starting init: /bin/sh exists but couldn't execute it (error -14)
  Kernel panic - not syncing: No working init found.  Try passing init= ...
  CPU: 0 PID: 1 Comm: init Not tainted 4.13.0-rc3-s3k-dev-00143-g7aa62e972a56 #56
  Call Trace:
    panic+0x108/0x250 (unreliable)
    rootfs_mount+0x0/0x58
    ret_from_kernel_thread+0x5c/0x64
  Rebooting in 180 seconds..

This is because in handle_page_fault(), the call to do_page_fault() has been
mistakenly enclosed inside an #ifdef CONFIG_6xx
