Add appropriate properties to devices in the Linksys WRT AC Series for the
mvneta driver to use hardware buffer management.
Also update "soc" ranges property and set the status of bm and bm-bppi
to "okay" (SRAM).

Something written somewhere in the Documentation / commit message which I can't find anymore gave me the impression that using the same for short doesn't make a difference. So I went with the pool IDs used for other similar boards for "consistency". Will send a v2 shortly using all independent pools using the IDs witch come most natural in context.
