MLK-19767: imx7ulp: configs: add a new macro for kernel dtb
The current u-boot configures the fdt_file environment variable
to the file name of that built together with u-boot. Sometimes
Linux kernel needs another dtb file other than the one built with
u-boot. For example, imx7ulp needs to build imx7ulp-evk-qspi.dts for
u-boot, but the kernel needs imx7ulp-evk.dts. Adding this new
macro to let the user have an option to specify a dtb file to run
Linux kernel.
