[En-Wei Wu]

BugLink: https://bugs.launchpad.net/bugs/2077384

SRU Justification:

[Impact]
With RTL8851BE and "Control WLAN radio" (in Dell BIOS setting) on, wifi function 
is not be disabled when we plug in the Ethernet cable. The issue is because the 
rtw89 driver doesn't have the hardware rfkill mechanism.

[Fix]
Backport the Realtek patch in linux-next:

[Test Plan]
