New GPUs still use the lower 2 bytes of the chip id (in whatever form
it comes) to signify silicon revision. Drop the warning that makes it
sound as if that was unintended.

Maybe just change it to ADRENO_6XX_GEN4?
That also applies to 700
Then the warn is warning about what it is supposed to ;-)
I guess this is coming from a6xx_gmu_fw_start()? I think we need a
different way to construct the gmu chipid, since the point of this was
to not depend on the low 8b having any particular meaning. Perhaps we
should just get the gmu chipid from the device table.
Guess that could work as well..
