[PATCH 1/2] cryptodev: update raw datapath API documentation

[Anoob Joseph <anoobj@marvell.com>]

Clarify the error codes returned by rte_cryptodev_raw_dp_ctx. Cryptodev
can return -ENOTSUP to indicate any unsupported features with raw APIs.

Remove redundant references about 'rte_cryptodev_raw_attach_session()'.
The API is not part of the specification.
