Bug description:
[SRU Justification]
[Impact]
System hang at suspend stress test with WCN6856 WiFi 6E - Qualcomm -
2R8DY.
[Fix]
Upstream firwmware WLAN.HSP.1.1-03125-QCAHSPSWPL_V1_V2_SILICONZ_LITE-3.6510.30
from
https://github.com/kvalo/ath11k-firmware/commit/c2d15c3e0843fe25a1697db4f6fe0c8ab0b639b9
should be used.
[Test Case]
Run suspend/resume stress test with fwts:
```
$ checkbox-cli run
com.canonical.certification::stress-suspend-30-cycles-with-reboots-automated
```
[Where problems could occur]
The proposed firmware is opaque to us, expect every possible
regression.
[Other Info]
At the time writing this pull request, this firmware blob is public released
in kvalo/ath11k-firmware only. While WCN6855 is enabled long time ago,
nominate
for Jammy/Lunar/Mantic. Noble branch is not yet created so omitted for now.
