It has been determined that the Ethernet stability fixes no longer require "snps,rxpbl", "snps,aal" and "snps,force_thresh_dma_mode" properties, [1][2] out of which the last two also induce performance penalties, so let's delete these properties from the relevant RK3328-based board dts(i) files. This commit completes the removal of these redundant "snps,*" DT properties that was started by a patch from Peter Geis.
