The variable(dma_flag) will be used by both fsl_ahci.c and fsl_sata.c,
Now we support the fsl_sata.c to DM mode and revert fsl_ahci.c(This
variable declare here). So we should Add this changed.

Hi Peng,

I'm missing an explanation for this revert (or even better for this
whole patch-set). Why are you doing this? Is the new DM driver
causing problems?

Thanks,
Stefan
