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.

This splits the gadget zero "source/sink" configuration into a standalone
"configuration driver", building on the composite gadget framework code.
It doesn't yet pull the original code out of gadget zero or update how
that driver is built.
Neither this, nor its sibling "loopback" configuration, is a function
driver that can be combined with other functions. (The host "usbtest"
driver wouldn't know how to deal with that!) However the code becomes
simpler because of this conversion, so it's a net win.
