clk/qcom: bubble up qcom_gate_clk_en() errors

If we try to enable a gate clock that doesn't exist, we used to just
fail silently. This may make sense for early bringup of some core
peripherals that we know are already enabled, but it only makes
debugging missing clocks more difficult.

Bubble up errors now that qcom_gate_clk_en() can return an error code to
catch any still-missing clocks and make it easier to find missing ones
as more complicated peripherals are enabled.
