Mark Johnston 72143e89bb Add qat(4)
This provides an OpenCrypto driver for Intel QuickAssist devices.  The
driver was initially ported from NetBSD and comes with a few
improvements:
- support for GMAC/AES-GCM, AES-CTR and AES-XTS, and support for
  SHA/HMAC-authenticated encryption
- support for detaching the driver
- various bug fixes
- DH895X support
