Bug Description
[Impact]
Some displays connect to the B&R PC device got the garbled display
[Fix]
The issue will disappear after commit 5ac860cc52540df
but these patches cannot be backported from 5.19 to 5.15. So add quirk
to force disable the i915 fastboot on the device to fix the abnormal display
[Test Case]
1. Connect the display and power on the B&R PC device
2. Check the display for boot up
[Where problems could occur]
Quirk only on the B&R PCs. Risk of regression is low.
