Jonas Gorski 68bf812b35 bcm63xx_enet: do not write to random DMA channel on BCM6345
commit d6213c1f2a upstream.

The DMA controller regs actually point to DMA channel 0, so the write to
ENETDMA_CFG_REG will actually modify a random DMA channel.

Since DMA controller registers do not exist on BCM6345, guard the write
with the usual check for dma_has_sram.
