[U-Boot] [PATCH v1 4/5] usb, g_dnl: make bcdDevice value configurable

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

Hi Heiko,

> add the possibility to set the bcdDevice number board specific.
> Therefore the weak function g_dnl_get_board_bcd_device_number()
> is introduced. Used on the siemens boards.
