mvebu: work around an ethernet tx scheduling fairness issue

The hardware queue scheduling is apparently configured with fixed
priorities, which creates a nasty fairness issue where traffic from one
CPU can starve traffic from all other CPUs.

Work around this issue by forcing all tx packets to go through one CPU,
until this issue is fixed properly.
