drivers/crypto/fsl : Allocate output ring with size aligned to CACHELNE SIZE
The output ring needs to be invalidated before enqueuing the job to SEC.
While allocation of space to output ring, it should be taken care that the
size is cacheline size aligned inorder to prevent invalidating valid data.
The patch also correct the method of aligning end of structs while flushing caches
Since start = align(start_of_struct), it is incorrect to assign
end = align(start + struct_size). It should instead be,
end = align(start_of_struct + struct_size).
