[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.

[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.
