crypto: marvell - Move tdma chain out of mv_cesa_tdma_req and remove it
Currently, the only way to access the tdma chain is to use the 'req' union from a mv_cesa_{ablkcipher,ahash}. This will soon become a problem if we want to handle the TDMA chaining vs standard/non-DMA processing in a generic way (with generic functions at the cesa.c level detecting whether the request should be queued at the DMA level or not). Hence the decision to move the chain field a the mv_cesa_req level at the expense of adding 2 void * fields to all request contexts (including non-DMA ones) and to remove the type completly. To limit the overhead, we get rid of the type field, which can now be deduced from the req->chain.first value. Once these changes are done the union is no longer needed, so remove it and move mv_cesa_ablkcipher_std_req and mv_cesa_req to mv_cesa_ablkcipher_req directly. There are also no needs to keep the 'base' field into the union of mv_cesa_ahash_req, so move it into the upper structure.
