Please replace this with something more specific for the actual
board. Preferably with the board manufacturer vendor prefix and
some sort of string for the board.

This doesn't get -v2 appended?

I don't think gcc-8994v1 ever got into a product, so we should
write the clk driver to treat qcom,gcc-msm8994 as the only
compatible string. Then this override isn't needed.
