km/scripts: load fdt_bid_kwkey.dtb when working with tftp
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.
