Bug Description

[SRU Justification]

[Impact]
On the intel ADL-U platform, the rtl8821ce suffers the beacon loss frequently because the driver doesn't received any beacon from AP. It causes the wpa-supplicant to reconnect again and again. Given it's critical to user experience and the urgent schedule, we need to SRU before getting approval.

[Fix]
Realtek release a fix to disable the PCI completion timeout on rtl8821ce so the PCI bus won't get stuck and can handed the received packets to the driver correctly.

[Test Case]
1. Connect the WiFi to internet by selecting a internet connected AP
2. ping 8.8.8.8 to check the internet connectivity for at least 5 minutes.
3. Make sure no 'CTRL-EVENT-BEACON-LOSS' event reported from wpa_supplicant

[Where problems could occur]
Risk should be Low. It's only applied for RTL8821CE to disable the completion timeout capability.

========== Original Bug Description ==========

[Summary]
Wireless keeps connection and loses connection repeatedly.

Below test cases are failed:
- wireless/wireless_connection_wpa_n_nm_wlp3s0
- after-suspend-wireless/wireless_connection_wpa_bg_nm_wlp3s0
- after-suspend-wireless/wireless_connection_wpa_ac_nm_wlp3s0
- after-suspend-wireless/wireless_connection_open_n_nm_wlp3s0
- after-suspend-wireless/wireless_connection_open_bg_nm_wlp3s0
- after-suspend-wireless/wireless_connection_open_ac_nm_wlp3s0

Issue is also observed on WVA4-DVT2-C1

[Steps to reproduce]
1. Boot into OS
2. Connect network by wireless
3. Run 'sudo apt update'

[Expected result]
Wireless connection won't break

[Actual result]
Wireless loses the connection and then connect network, after a while, issue happens again.

[Failure rate]
10/10
