[Impact]
During hotplug built-in hdmi, the error message show up.
#REG_WAIT timeout for yellow Carb

[Fix]
This tends to take miliseconds in certain scenarios and we'd rather not
wait that long. Due to how this interacts with det size update and
locking waiting should not be necessary as compbuf updates before
unlock.

Add a watch for config error instead as that is something we actually do
care about.

[Test Case]
1. Plug and unplug hdmi
2. cant get the error message in dmesg.

[Where problems could occur]
