usb: hub: remove CONFIG_USB_HUB_MIN_POWER_ON_DELAY
Now that we wait the correct specification-mandated time at the end of usb_hub_power_on(), I suspect that CONFIG_USB_HUB_MIN_POWER_ON_DELAY has no purpose. For cm_t35.h, we already wait longer than the original MIN_POWER_ON_DELAY, so this change is safe. For gw_ventana.h, we will wait as long as the original MIN_POWER_ON_DELAY iff pgood_delay was at least 200ms. I'm not sure if this is the case or not, hence I've CC'd relevant people to test this change.
