Kernel driver should configure KBL's DDI buffer setting for AML ULX as well. So far, driver would load DDI translation table that used for KBL H/S platform and apply it on AML devices. But AML is belong to ULX series. This change will lead driver to apply KBL-Y's DDI table for AML devices to avoid unexpected eDP/DP signal quality issue.
