The binman_linux.dtsi is a fork of binman.dtsi, just change the first
section image from the "u-boot" to "linux". Note that the filename
is also changed. In binman.dtsi, the filename of u-boot section filename
is called "u-boot-nodtb.bin". In binman_linux.dtsi, the filename should
be called "Image", which is located in linux/arch/riscv/boot.
