[U-Boot] [PATCH 3/4] km/scripts: load fdt_bid_kwkey.dtb when working with tftp

[Valentin Longchamp]

From: Holger Brunck <holger.brunck at keymile.com>

When loading the dtb file via tftp we should load the one which matches
boardId and hwKey and not a common one for the boardname. We have boards
were different hwKeys are used and then we may load an incorrect dtb
file. If no fdt_bid_kwkey.dtb file is not a fallback to boardname.dtb is used.
