Since the dwc2 hcd driver is currently not looking for a clock node during
init, we should not completely fail if there isn't a clock provided.
For dual-role mode, we will only fail init for a non-clock node error. We
then update the HCD to only call gadget funtions if there is a proper clock
node.
We have to add clock management for hcd, and I think it is better to
do it before more Socs use this driver, isn't it?
I have do something in my RFC patches, but I think I still do it in a
wrong way.
Can we just handle all the clock thing in platform?
Balbi suggested in my patch that we can "hide" clk_enable()/disable() under
->runtime_resume()/->runtime_suspend() and linux driver model.
Can this be in platform driver?
