The pch_gbe_configure_rx() function open-codes the equivalent of pch_gbe_disable_dma_rx(). Remove the duplication by moving pch_gbe_disable_dma_rx(), and pch_gbe_enable_dma_rx() for consistency, to be defined earlier than pch_gbe_configure_rx() and have pch_gbe_configure_rx() call pch_gbe_disable_dma_rx() rather than duplicate its functionality.
