Fix regression introduced by commit 796211b7953 ("mmc: atmel-mci: add
pdc support and runtime capabilities detection") which removed the need
for CONFIG_MMC_ATMELMCI_DMA but kept the Kconfig-entry as well as the
compile guards around dma_release_channel() in remove(). Consequently,
DMA is always enabled (if supported), but the DMA-channel is not
released on module unload unless the DMA-config option is selected.
Remove the no longer used CONFIG_MMC_ATMELMCI_DMA option completely.
