Aneesh Kumar K.V ef629cc5bf powerc/mm/hash: Reduce hash_mm_context size 
Allocate subpage protect related variables only if we use the feature.
This helps in reducing the hash related mm context struct by around 4K

Before the patch
sizeof(struct hash_mm_context)  = 8288

After the patch
sizeof(struct hash_mm_context) = 4160
