Validate Workaroound to SPEC-1763 for FF release

I just pushed https://gerrit.automotivelinux.org/gerrit/16855 to FF.

This introduces a workaround at 4A level: the startup is delayed until the BT device and Bluetooth-Manager are available. And if no BT is detected, the script tries to bail out as early as possible (8 secs max if no BT is detected).

So we need now some help to validate the solution on the boards for FF.

This table is to be updated to fill the test results:

How to validate: after bootup, run:

journalctl | grep 4AWAITBT

This will give the result of wait loop (the script 4a_wait_bt.sh introduced in the W/A). When BT is enabled, the last line should be:

{{ 4AWAITBT 4A now starting... }}

Otherwise (no BT controller), it should be:

4AWAITBT TIMEOUT REACHED

To check if 4A BT audio is enabled:

journalctl -u afm-service-agl-service-audio-4a-*@0.service --no-pager -p4 | grep "No bluetooth receiver detected"

 There should be no ouput. If you see a warning message with "No bluetooth receiver detected", it means that BT audio is disabled (it should be if we don't have any BT adapter)
