build: Use filechk rules to create and update u-boot.lds
Prior to this patch, the top-level linker script u-boot.lds used a simple $(call if_changed) check when generated. That mechanism misses cases where a possible include file change induces a change in the u-boot.lds too. This patch converts it to a stronger check using ($call filechk) that will also notice differences in file contents and will catch changes due to pre-processing as well.
