From: Vardan Mikayelyan <mvardan@xxxxxxxxxxxx>
No-op change, only rename.
This code was misnamed originally. It was only responsible for partial
power down and not for hibernation.
Rename core_params->hibernation to core_params->power_down,
dwc2_set_param_hibernation() to dwc2_set_param_power_down().
