[U-Boot] [PATCH v2 2/4] fastboot: call board_usb_init() to enable usb

[Lukasz Majewski <l.majewski@samsung.com>]

Hi Dileep,

> g_dnl_gadget_register() fails for dra7xx dwc3 gadget when running
> cmd_fastboot. Calling board_usb_init() to fix this.
> fastboot command is now added with an optional controller index
> argument with default value as 0, to facilitate configurable
> controller index.

Since I'm not CC'ed to all patches, I assume that this work would go
via other tree?
