[PATCH v3 10/13] crypto: sun4i-ss: add the CRYPTO_ALG_KERN_DRIVER_ONLY flag

[Antoine Tenart]

The CRYPTO_ALG_KERN_DRIVER_ONLY flag is set for hardware accelerated
ciphers accessible through a kernel driver only. This is the case for
ciphers exposed by the sun4i-ss driver. This patch sets this flag.
