crypto: talitos - add chaining of arbitrary number of descriptor for the SEC1

Browse source

The SEC1 hardware can process a chain of descriptors without host
intervention. Only the hash implementation currently use this feature,
but with a chain of at most 2 descriptors added in commit 37b5e8897e
("crypto: talitos - chain in buffered data for ahash on SEC1").

Add supports for chaining an arbitrary number of descriptors in a chain.

Adapt the ahash implementation to make it compatible.
