Makefile: ensure DTB doesn't overflow into initial stack
With CONFIG_SYS_INIT_SP_BSS_OFFSET enabled, the initial (pre-relocation)
stack is placed some distance after bss_start. The control DTB is appended
to the U-Boot binary at bss_start. If the DTB is too large, or the SP BSS
offset too small, then the initial stack could corrupt the DTB. Enhance
the Makefile to check whether this is likely to occur.
