[PATCH 20/22] ARM: k3: BeaglePlay: generate FIT image

[Sascha Hauer <s.hauer@pengutronix.de>]

The K3 SoCs are currently not fully bareboxified, we still need
U-Boot to bring up the SoC. Only the last stage, u-boot.img can be
replaced by barebox. Create a FIT image to generate an image
suitable for replacing u-boot.img.
