   - Performance improvement for HMAC DRBG.

  Drivers:

   - Use generic crypto engine in omap-des.
   - Merge ppc4xx-rng and crypto4xx drivers.
   - Fix lockups in sun4i-ss driver by disabling IRQs.
   - Add DMA engine support to ccp.
   - Reenable talitos hash algorithms.
   - Add support for Hisilicon SoC RNG.
   - Add basic crypto driver for the MXC SCC.
