Subject: [RFC PATCH v2 6/7] dt-bindings: arm: mediatek: Remove SKU specific compatibles for Google Krane

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. Thus we no longer have
to specify separate compatible strings for each of them.

Remove the SKU specific compatible strings for Google Krane.
