Without this patch, u-boot-tpl.dtb is always copy from u-boot-spl.dtb which
doesn't apply fdtgrep with "-b u-boot,dm-tpl".
Sometimes, the platform with critical sram size requires u-boot-tpl.dtb as
smaller as possible, so we use "u-boot,dm-tpl" prop to idendify what the
tpl really needs.
Rules:
"u-boot,dm-tpl": include node with prop for u-boot-tpl.dtb;
"u-boot,dm-spl": include node with prop for u-boot-spl.dtb;
"u-boot,pre-reloc": include node with prop for u-boot-tpl.dtb and u-boot-spl.dtb;
