[PATCH v8 0/2] Modularization of DFL private feature drivers

[Xu Yilun <yilun.xu@intel.com>]

This patchset makes it possible to develop independent driver modules
for DFL private features. It also helps to leverage existing kernel
drivers to enable some IP blocks in DFL.


Patch #1: Introduce the dfl bus, then dfl devices could be supported by
          independent dfl drivers.
Patch #2: An example of the dfl driver for N3000 nios private feature.


Main changes from v7:
- remove the dfl_info_attr macro in dfl framework.
- add sysfs interfaces for retimer mode in dfl-n3000-nios, also doc update.
- delete duplicated sysfs interfaces description in dfl-n3000-nios doc.
- minor fixes.

  fpga: dfl: create a dfl bus type to support DFL devices
  fpga: dfl: add support for N3000 Nios private feature
