usb: gadget: Move CONFIG_USB_GADGET to Kconfig
The description was borrowed from kernel. "tristate" type was changed
to "bool" (I believe we don't support modules for u-boot yet, right?).
CONFIG_USB_GADGET requires CONFIG_USB to be defined too, so add it along
as well.
Definitions were added to defconfig files in a way that
"make savedefconfig" generates exactly the same file as used defconfig.
