Fix regression introduced by commit 796211b7 ("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.

Defconfig file for at91sam9g45 SoC family:
at91sam9g45, at91sam9g46, at91sam9m10, at91sam9m11.
The Atmel Evaluation Kit for this family is the at91sam9m10g45ek.

It is so useful for automatic compile tests...
