Since the commit 8a469ee35606 ("arm64: dts: rockchip: Add txpbl node for RK3399/RK3328"), having "snps,txpbl" properties defined as Ethernet stability fixes in RK3328-based board dts(i) files is redundant, because that commit added the required fix to the RK3328 SoC dtsi, so let's delete them. 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.
