Bug description:
  [SRU Justification]

  [Impact]
  rtl9921ce-dkms may fail to compile dkms modules on devices with v5.5 kernel or newer due to kernel data structure changes.

  [Fix]
  Following changes required with modifications to fix such errors:
  * commit ff74b75511c5 ("convert file_operations structs to proc_ops structs for compatibility with linux 5.6") from https://github.com/tomaspinho/rtl8821ce .
  * commit 5e7d1302d3c4 (".mgmt_frame_register -> .update_mgmt_frame_registrations")  from https://github.com/tomaspinho/rtl8821ce .
  * Additional fix to "core/rtw_security.c" for v5.8 kernels.

  [Test Case]
  Verified with kernels:
  * 5.4.0-26-generic
  * 5.6.0-1010-oem
  * 5.7.0-9-generic
  * 5.8.0-1-generic

  [Regression Potential]
  Low. The patches are to adopt new interface changes when compiled against new kernels. For existing users with older kernels, they're not affected. For those with new kernels they're still fine as that's what new kernels do.
