[PATCH 3/4] imx: image: use 'u-boot-dtb.img' filename for SPL payload

[Piotr Dymacz]

For targets in U-Boot which were migrated to DM, the correct binary
image filename will be 'u-boot-dtb.img'. For backward compatibility,
keep support for both files and use the one which was generated with
our 'uboot-imx' package.

See also 'CONFIG_SPL_FS_LOAD_PAYLOAD_NAME' and 'CONFIG_OF_CONTROL' in
mainline U-Boot sources.
