Seth Jennings 0e16aafb12 powerpc/crypto: add 842 hardware compression driver
This patch adds the driver for interacting with the 842
compression accelerator on IBM Power7+ systems.

The device is a child of the Platform Facilities Option (PFO)
and shows up as a child of the IBM VIO bus.

The compression/decompression API takes the same arguments
as existing compression methods like lzo and deflate.  The 842
hardware operates on 4K hardware pages and the driver breaks up
input on 4K boundaries to submit it to the hardware accelerator.

Support for Power7+ in-Nest encryption acceleration. This
module supports acceleration for AES and SHA2 algorithms. If you
choose 'M' here, this module will be called nx_crypto.
