usb: dwc2: Update dwc2_handle_usb_suspend_intr function.

To avoid working in two modes (partial power down and hibernation) changed conditions for entering partial power down or hibernation. Instead of checking hw_params.power_optimized and hw_params.hibernation now checking power_down param which already set to one of the options (Hibernation or Partial Power Down) based on OTG_EN_PWROPT.
