kbuild: fix build rule of u-boot-spl.dtb
The build command of u-boot-spl.dtb is not constant, but dependent on CONFIG_OF_SPL_REMOVE_PROPS. Use $(call if_changed,...) so that the change of CONFIG_OF_SPL_REMOVE_PROPS is detected. Also, add tools/fdtgrep to the dependency to make sure u-boot-spl.dtb is generated by the up-to-date fdtgrep in case the tool is modified.
