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.

Changes in v2:
- Changed fastboot command to facilitate passing controller
index
- Added board_usb_cleanup()
This patch considers the following change by Inha Song, without which the build will be broken on BeagleBone Black platform https://patchwork.ozlabs.org/patch/430303/

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