crypto: add i.MX6 CAAM support
Add the i.MX6 crypto core CAAM with support for the random number
generator.
The core itself works with jobrings in which descriptors can be
queued/dequeued for processing. Depending on descriptor type
the CAAM unit then either produces random numbers or decrypts/encrypts
data.
The code is based on the Linux v4.1 driver of the same name
without all the crypto/hashing components.
