It's not a clk controller, so I don't see how that makes sense. There
are clk/reset controllers on qcom platforms, and so we've combined them
into the same overall driver there because those resets affect clk
operations and vice-versa. But this looks like some sort of reset in the
phy or the controller itself and isn't the "clk type" resets that we
implement in drivers/clk/qcom/
