powerpc/kuep: Remove 'nosmep' boot time parameter except for book3s/64 Deactivating KUEP at boot time is unrelevant for PPC32 and BOOK3E/64. Remove it. It allows to refactor setup_kuep() via a __weak function that only PPC64s will overide for now.

powerpc/32s: Move KUEP locking/unlocking in C This can be done in C, do it. Unrolling the loop gains approx. 15% performance. From now on, prepare_transfer_to_handler() is only for interrupts from kernel.

powerpc/32s: Only build hash code when CONFIG_PPC_BOOK3S_604 is selected It is now possible to only build book3s/32 kernel for CPUs without hash table. Opt out hash related code when CONFIG_PPC_BOOK3S_604 is not selected.

powerpc/32s: Move _tlbie() and _tlbia() in a new file _tlbie() and _tlbia() are used only on 603 cores while the other functions are used only on cores having a hash table. Move them into a new file named nohash_low.S Add mmu_hash_lock var is used by both, it needs to go in a common file.
