[PPC] Fix COMMON symbol warnings

We get the following warnings in various ARCH=ppc builds:

WARNING: "ee_restarts" [arch/ppc/kernel/built-in] is COMMON symbol
WARNING: "fee_restarts" [arch/ppc/kernel/built-in] is COMMON symbol
WARNING: "htab_hash_searches" [arch/ppc/mm/built-in] is COMMON symbol
WARNING: "next_slot" [arch/ppc/mm/built-in] is COMMON symbol
WARNING: "mmu_hash_lock" [arch/ppc/mm/built-in] is COMMON symbol
WARNING: "primary_pteg_full" [arch/ppc/mm/built-in] is COMMON symbol
WARNING: "global_dbcr0" [arch/ppc/kernel/built-in] is COMMON symbol

Switch to local symbols for ee_restarts, fee_restarts, and global_dbcr0 and
global symbols for mmu_hash_lock, next_slot, primary_pteg_full, and
htab_hash_searches.

(except mmu_hash_lock which is global) and
space directive instead.
