usb: gadget: Allow up to 900mA current draw for SuperSpeed

Browse source 
Currently 500mA is used as max allowable current to draw over
USB VBUS. However in SuperSpeed a gadget may draw up to 900mA
Update the CONFIG_USB_GADGET_VBUS_DRAW's allowable range to
be up to 900.

connected speed: for SuperSpeed and up it is 2 - 900 mA, but
connections at High Speed or slower will be capped at 500 mA;
0 mA would be legal, but can make some hosts misbehave.
