FPGA DFL Changes for 5.4

This pull-request contains the FPGA DFL changes for 5.4

- The first three patches are cleanup patches making use of dev_groups and
  making the init callback optional.
- One patch adds userclock sysfs entries that are DFL specific
- One patch exposes AFU port disable/enable functions
- One patch adds error reporting
- One patch adds AFU SignalTap support
- One patch adds FME global error reporting
- The final patch is a documentation patch that decribes the
  virtualization interfaces

This patchset requires the 'dev_groups_all_drivers' tag from drivers
core for the dev_groups refactoring as well as the DFL changes already
in char-misc-next.
