Currently dwc3 gadget processes the suspend interrupt event only
if the device is in configured state. But consider a case where
device is not configured and got suspend interrupt, in that case
our gadget would still use 100mA as composite_suspend didn't happen.
But battery charging specification (BC1.2) expects a downstream
device to draw less than 2.5mA when unconnected OR suspended.

And while resuming, the gadget can draw upto 100mA if its not
configured, but the current implementation of composite_resume
doesnt consider the case of unconfigured device. This series
addresses the above mentioned issues.
