crypto: marvell/cesa - add a new driver for Marvell's CESA The existing mv_cesa driver supports some features of the CESA IP but is quite limited, and reworking it to support new features (like involving the TDMA engine to offload the CPU) is almost impossible. This driver has been rewritten from scratch to take those new features into account. This commit introduce the base infrastructure allowing us to add support for DMA optimization. It also includes support for one hash (SHA1) and one cipher (AES) algorithm, and enable those features on the Armada 370 SoC. Other algorithms and platforms will be added later on.

crypto: marvell/cesa - add TDMA support The CESA IP supports CPU offload through a dedicated DMA engine (TDMA) which can control the crypto block. When you use this mode, all the required data (operation metadata and payload data) are transferred using DMA, and the results are retrieved through DMA when possible (hash results are not retrieved through DMA yet), thus reducing the involvement of the CPU and providing better performances in most cases (for small requests, the cost of DMA preparation might exceed the performance gain). Note that some CESA IPs do not embed this dedicated DMA, hence the activation of this feature on a per platform basis.
