usb gadget: USB_GADGET_VBUS_DRAW Kconfig option
Offer a "how much VBUS power to request" configuration option for USB gadgets that aren't using board-specific customization of their gadget or (composite) configuration drivers. Also remove a couple pointless "depends on USB_GADGET" bits from the Kconfig text; booleans inside an "if USB_GADGET" will already have that dependency. Based on a patch from Justin Clacherty.
