ANDROID: GKI: USB: pd: Extcon fix for C current



This is a partial cherrypick.

It is required to notify device as selfpowered and bmaxpower as zero
even for non PD capable devices based on Type C current. Hence notify
as selfpowerer in bmAttributes of configuration descriptor in case of
medium or high Type C current.
