This patch fixes kernel build error like this.

Run command "MACHINE=rock2-square bitbake linux-yocto" and get the error.

|   SYNC    include/config/auto.conf
|   GEN     Makefile
| make[2]: *** No rule to make target 'arch/arm/boot/dts/rk3288-rock2-square.dtb'.  Stop.

You can run "MACHINE=tinker-board bitbake linux-yocto" to test it.

I think another patch would fix it.
