mtd: rawnand: Provide a helper to get chip->data_buf
We plan to move cache related fields to a pagecache struct in nand_chip
but some drivers access ->pagebuf directly to invalidate the cache
before they start using ->data_buf.
Let's provide an helper that returns a pointer to ->data_buf after
invalidating the cache.
