According to patch "drm/i915/aml: Introducing Amber Lake platform"
(e364672477a1). Amber Lake uses the same gen graphics as Kaby Lake.
And it is the member of KBL ULX series.

So far, IS_KBL_ULX macro did not include AML platform. It may caused
driver load DDI translation table for KBL H/S series for AML system.
The change will lead driver to apply translation table for KBL Y for
AML device to avoid unexpected eDP/DP signal quality issue.
