In case when a hub is connected to DWC2 host
auto suspend occurs and host goes to
hibernation. When any device connected to hub
host hibernation exiting incorrectly.
- Added dwc2_hcd_rem_wakeup() function call to
exit from suspend state by remote wakeup.
- Increase timeout value for port suspend bit to be set.
