crypto: Add support for Intel(R) QuickAssist

Hi,
This patchset adds support for Intel(R) QuickAssist Technology (QAT) and DH895xCC hardware accelerator.
First patch adds a common infractructure that will be used by all QAT devices.
Second patch adds a firmware loader module that is used to load the microcode to the acceleration engines and start them.
Third patch adds dh895xcc hardware specific code, which hooks to the common infrastructure and provides acceleration for
the following algorithms:
authenc(hmac(sha1),cbc(aes)), authenc(hmac(sha256),cbc(aes)), authenc(hmac(sha512),cbc(aes))
Fourth patch updates makefiles etc.

More info on the hardware accelerator and the Quick Assist Technology can be found on:
https://01.org/packet-processing/intel%C2%AE-quickassist-technology-drivers-and-patches

Update to makefiles etc.
Don't update the firmware/Makefile yet since there is no FW binary in the crypto repo yet. This will be added later.

v3 - removed change to ./firmware/Makefile

Hi,
I just realized that patch 1 and 2 never made it to [email protected].
The reason is that vger.kernel.org blocks messages longer than 100 000 characters.
Both my patches were bigger. I need to brake it into more patches so version 4 will be sent out soon.
Sorry for making so much noise.
Regards,
Tadeusz

Add a function pointer declaration check to the
test for blank line needed after declarations.
