Bug description:
[SRU Justifcation]
[Impact]
On platforms with RTL8851BE/RTL8852BE, bluetooth mouse/keyboard may not work
smoothly with WiFi connection activated.
[Fix]
Proposed firmware upstreamed as:
* 2afd1423e476 ("rtw89: 8852b: update fw to v0.29.29.5")
* 7a916315fb28 ("rtw89: 8852b: update fw to v0.29.29.4")
* 02df6e4f03c0 ("rtw89: 8851b: update fw to v0.29.41.3")
[Test Case]
1. Install Ubuntu 22.04 on SUT with RTL8851BE / 8852BE Wlan card
2. Connected BT KB/MS, and then connected WIFI, select an AP to connect
3. Check BT mouse/keyboard, mouse movement, keyboard key pressing not respond
smoothly.
[Where problems could occur]
This updates opaque firmware blobs, so anything could happen. With
verifications
from multiparties, it improves the stability and no other problem found so
far.
[Other Info]
On Lunar, we don't have RTL8851BE enabled, so the related commits are omitted.
On Mantic and oem-6.5/jammy, we have both.
