OpenCAPI coherent accelerator support

In linux kernel since version 3.10 (release Date: 2013-06-30)  
Select this option to enable the ocxl driver for Open
Coherent Accelerator Processor Interface (OpenCAPI) devices.

OpenCAPI allows FPGA and ASIC accelerators to be coherently
attached to a CPU over an OpenCAPI link.

The ocxl driver enables userspace programs to access these
accelerators through devices in /dev/ocxl/.

This is not to be confused with the support for IBM CAPI
accelerators (CONFIG_CXL), which are PCI-based instead of a
dedicated OpenCAPI link, and don't follow the same protocol.

If unsure, say N.
