I checked the exact numbers we're talking about here: enabling
CONFIG_HAS_DMA on rsk7269_defconfig adds 10KB of extra vmlinux
size, which doesn't seem too bad:

   text	   data	    bss	    dec	    hex	filename
3295084	1111396	 112264	4518744	 44f358	vmlinux-before
3302836	1113652	 112264	4528752	 451a70	vmlinux-after
