This bit is not correct, the power domain would not have been disabled
until you enable runtime PM as part of this very patch.

I noticed similar claims have incorrectly been made in the past, for
example, in the recent:

2a541abd9837 clk: qcom: gcc-sc8280xp: Add runtime PM

and older:

a91c483b42fa ("clk: qcom: videocc-sm8250: use runtime PM for the clock controller")
