against v4 are sysfs related code rework to address comments on v4.

Please help to take a look. Thanks!

Main changes from v4:
  - convert code to use dev_groups for sysfs entries (#2, #3, #4, #6, #8).
  - clean up for empty init function after remove sysfs add/remove (#1).
  - introduce is_visible for sysfs groups (#3, #4, #6, #8).
  - remove revision sysfs entries (#4, #6, #8).
  - improve naming on shared functions (#5).
  - reorganize sysfs entries for port and fme error reporting (#6, #8).

Main changes from v3:
  - drop avx512 partail reconfiguration patch for now.
  - split dfl_fpga_cdev_config_port to 2 functions *_release/assign_port
    (#1).
  - split __dfl_fpga_cdev_config_port_vf into 2 functions with locking
    added (#2).
  - improve description in sysfs doc to avoid misunderstanding (#3).
  - switch to boolean in sysfs entry store function (#3).
  - remove dev_dbg in init/uinit callback function (#7, #9, #11).
