[U-Boot] mkimage for ls1021a-twr.dtb

[Alison Wang]

For dtb, you can use ls1021a-twr.dtb directly. No need to use mkimage.

To generate uImage, you can use mkimage for it.

mkimage -A arm -O linux -T kernel -C none -a 0x80008000 -e 0x80008000 -n "Linux Kernel" -d arch/arm/boot/zImage uImage.ls1021a
