  SM8150 has (at least) two GPU speed bins. With the support added on the
driver side, wire up bin detection in the DTS to restrict lower-quality
SKUs from running at frequencies they were not validated at.

Just like sm8250, you can probably delete the:

    /* note: downstream checks gpu binning for 675 Mhz */

comment right above this node.
