The cbas node is used to describe base detection functionality in the ChromeOS EC, which is used for units that have a detachable keyboard and thus rely on this functionality to switch between tablet and laptop mode. Despite the original commit having added the cbas node to the mt8183-kukui.dtsi, not all machines that include it are detachables. In fact all machines that include from mt8183-kukui-jacuzzi.dtsi are either clamshells (ie normal laptops) or convertibles, meaning the keyboard can be flipped but not detached. The detection for the keyboard getting flipped is handled by the driver bound to the keyboard-controller node in the EC. Move the base detection node from the base kukui dtsi to the dtsis where all machines are detachables, and thus actually make use of the node.
