ARM: sun5i: cryptographic engine support

Hello,

This series adds the cryptographic engine support to sun5i SoCs. This is based on top of v4.12-rc1 and was tested on a CHIP. The series begins with fixes and improvements. The series is available at:
https://github.com/atenart/linux v4.12-rc1/sun5i-crypto

The 8 first patches are reworks and cosmetic improvements.

Patch 9 moves the cipher part of the sun4i-ss driver from the ablkcipher API to the newer skcipher API.

Patch 10 adds the CRYPTO_ALG_KERN_DRIVER_ONLY flag for ciphers exposed by the sun4i-ss driver.

Patch 11 fixes the crypto framework selftests on the CHIP. It might fix other users too.

Patch 12 adds a cryptographic engine node for sun5i SoCs.

Thanks,
Antoine

Since v1:
- Fixed a typo.
- Made the CRYPTO_ALG_KERN_DRIVER_ONLY flag addition in a dedicated patch.

Antoine Tenart (12):
crypto: sun4i-ss: group variable definitions in sun4i_hash()
crypto: sun4i-ss: remove conditional checks against 0
crypto: sun4i-ss: use lower/upper_32_bits helpers
crypto: sun4i-ss: cannot use DMA is the request is 0 length
crypto: sun4i-ss: do not dynamically set parts of the last buffer to 0
crypto: sun4i-ss: simplify the pad length calculation
crypto: sun4i-ss: simplify the appended bit assignment
crypto: sun4i-ss: use GENMASK to generate masks
crypto: sun4i-ss: move from ablkcipher to skcipher API
crypto: sun4i-ss: add the CRYPTO_ALG_KERN_DRIVER_ONLY flag
crypto: sun4i-ss: fix large block size support
