mtd: spi-nor: Separate preparation and locking

While this operation will remain a single function call in the end,
let's extract the logic of the [un]prepare calls within their own static
helper. We will soon add new flavors of the *_[un]prepare_and_[un]lock()
helpers, having the preparation logic outside will save us from duplicating
code over and over again.

There is no functional change.
