crypto/fsl: fix BLOB encapsulation and decapsulation
The blob_encap and blob_decap functions were not flushing the dcache
before passing data to CAAM/DMA and not invalidating the dcache when
getting data back.
Therefore, blob encapsulation and decapsulation failed with errors like
the following due to data cache incoherency:
"40000006: DECO: desc idx 0: Invalid KEY command"
To ensure coherency, we require the key_mod, src and dst buffers to be
aligned to the cache line size and flush/invalidate the memory regions.
The same requirements apply to the job descriptor.
Tested on an i.MX6Q board.
