usb: dwc2: Add hibernation field into dwc2_hw_params

Browse Source 
Add parameter and it's initialization, needed for hibernation.

Reimplement dwc2_set_param_power_down() to support hibernation too.
Now 'power_down' parameter can be initialized with 0, 1 or 2.
0 - No
1 - Partial power down
2 - Hibernation
