[PATCH] arm64: dts: rockchip: Delete redundant RK3328 GMAC stability fixes

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
the "snps,rxpbl" and "snps,aal" properties, [1] out of which the latter also
induces 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,*" properties
that was started by a patch from Peter Geis. [2]
