In cases where the same Chromebook model is manufactured with different components (MIPI DSI panels, MIPI CSI camera sensors, or trackpad / touchscreens with conflicting addresses), a different SKU ID is allocated to each specific combination. This SKU ID is exported by the bootloader into the device tree, and can be used to "discover" which combination is present on the current machine. Merge the separate Krane dtsi/dts files into one shared for all SKUs. A new device node is added for the alternative panel. Both it and the original panel are marked as "fail-needs-probe-panel" to let the hardware prober handle it. Also move the cros_ec node so that all node references are ordered alphabetically.
