Mathias Nyman 2bbd38fcd2 xhci: dbc: enable back DbC in resume if it was enabled before suspend 
DbC is currently only enabled back if it's in configured state during
suspend.

If system is suspended after DbC is enabled, but before the device is
properly enumerated by the host, then DbC would not be enabled back in
resume.

Always enable DbC back in resume if it's suspended in enabled,
connected, or configured state
