[U-Boot] [PATCH 2/4] usb: Fastboot function config for better consistency with other functions

[Lukasz Majewski]

Hi Paul,

> USB download gadget functions such as thor and dfu have a separate
> config option for the USB gadget part of the code, independent from
> the command part. This switches the fastboot USB gadget to the same
> scheme, for better consistency.

I will test this patch on my devices and then pull it to u-boot-dfu
tree.

Thanks for your work!
