dpaa: Add QorIQ Security Engine (SEC) driver

The QorIQ Security Engine (SEC) generally fits into the Data Path
Acceleration Architecture, accelerating cryptographic operations.

Currently this driver does not use the QMan interface, instead relying
on the job rings, as Linux also does, to reduce complexity until needed
for network protocol acceleration, like IPSec and OpenVPN.

Initial testing via `openssl speed -engine devcrpto -evp aes-128-cbc`
yields a ~200x throughput improvement, from 105MB/s to more than 20GB/s
for 16k block sizes.
