Overview:
Intel(R) QuickAssist Technology (Intel(R) QAT) provides hardware
acceleration for offloading security, authentication and compression
services from the CPU, thus significantly increasing the performance and
efficiency of standard platform solutions.
This commit introduces:
- Intel® 4xxx Series platform support.
- QuickAssist kernel API implementation update for Generation 4 device.
Enabled services: symmetric cryptography and data compression.
- Increased default number of crypto instances in static configuration
for performance purposes.
OCF backend changes:
- changed GCM/CCM MAC validation policy to generate MAC by HW
and validate by SW due to the QAT HW limitations.

This header duplicates a few #defines in "adf_cfg_strings.h". The
latter header does not use the unneeded parentheses, but if a C file
includes both of these headers, clang raises an error because the macro
is redefined with a different value.

QAT in-tree driver ported from out-of-tree release available
from 01.org.
The driver exposes complete cryptography and data compression
API in the kernel and integrates with Open Crypto Framework.
Details of supported operations, devices and usage can be found
in man and on 01.org.

A replacement QAT driver will be imported, but this replacement does not
support Atom C2xxx hardware. So, the existing driver will be kept
around to provide opencrypto offload support for those chipsets.

This centralizes the check for valid nonce lengths for AES-GCM.
While here, remove some duplicate checks for valid AES-GCM tag lengths

Otherwise qat_detach() may attempt to deregister an unrelated crypto
driver if an error occurs in qat_attach() before crypto_get_driverid()
is called, since 0 is a valid driver ID.

If firmware_get() fails to find a loaded firmware image, it searches for
candidate KLDs to load. It will search for a KLD containing a module
with the same name as the requested image, and failing that, will load a
KLD with the same basename as the requested image.
The module name given by fw_stub.awk is simply "<mangled KLD name>_fw".
QAT firmware modules contain two images, neither of which match either
of the names used during lookup, so automatic loading of firmware images
after mountroot does not work. Work around this by using the same
string for the first image name and for the KLD basename.

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
