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.
