The introduction of support for Apple board types inadvertently changed the precedence order, causing hybrid SMBIOS+DT platforms to look up the firmware using the DMI information instead of the device tree compatible to generate the board type. Revert back to the old behavior, as affected platforms use firmwares named after the DT compatible.
