mvebu: limit mvneta tx queue workaround to 32 bit SoC
This patch has been carried since introduction throughout every kernel major bump and no one has tested if the later kernels improved the situation. The Armada 3720 SoC can only process GbE interrupts on Core 0 and this is already limited in all stable kernels, so ditch this workaround for 64 bit SoCs.
