Cédric Le Goater 363248e8c9 mmu-hash64: fix Virtual Page Class Key Protection 
commit f80872e21c (mmu-hash64: Implement
Virtual Page Class Key Protection) added a new page protection
mechanism based on page keys and the AMR register to control access.

The AMR register allows or prohibits reads and/or writes on a page
depending on the control bits associated to the key. A store or a load
is only permitted if the associate bit is 0 (Power ISA), and not 1 as
the code is currently doing. This patch modifies ppc_hash64_amr_prot()
to correct the protection check.

This issue was unvailed by commit ccfb53ed6360cac0d5f6f7915ca9ae7eed866412
(target-ppc: fix Authority Mask Register init value) which changed the
initialisation value of the AMR register to 0.
