[PATCH 00/10][SRU][F/OEM-5.6] Fix Realtek 8723DE disconnects unsolicitedly when Bluetooth is paired: Reason: 23=IEEE8021X_FAILED

[You-Sheng Yang]

BugLink: https://bugs.launchpad.net/bugs/1878147

[Impact]
Existing Wi-Fi connection may be deauthenticated unsolicitedly with
reason 23=IEEE8021X_FAILED when the system is also paired with a
Bluetooth device. A WLAN passphrase dialog propmpts, and system
disconnects from network:

  wlp5s0: deauthenticated from a4:56:30:cc:0f:30 (Reason: 23=IEEE8021X_FAILED).

[Fix]
Realtek proposed a fix[1] to linux-wireless consisting of three patches.

  rtw88: coex: 8723d: set antanna control owner
  rtw88: coex: 8723d: handle BT inquiry cases
  rtw88: fix EAPOL 4-way failure by finish IQK earlier

The third one actually duplicates the fix we have for bug 1871300 also
from Realtek and was claimed critical to this issue, therefore those for
bug 1871300 are reverted in favor of the new one.

Also revert that Ubuntu sauced "rtw88: 8723d: Add coex support" commit
and replace it with the upstream one, and cherry picked two more debugfs
changes due to dependency to bt coex functionality.

[Test Case]
1. Associate to a WLAN,
2. Pair with some Bluetooth device, e.g. headset,
3. Run a stress test script to disconnect and reconnect Wi-Fi for 200
   runs,
4. Make sure Wi-Fi passphrase dialog doesn't prompt at the end of the
   test.

[Regression Potential]
Low. These changes are mostly about rtl8723de or 11n, which is also for
8723de.
