mmc: at91/avr32/atmel-mci: fix DMA-channel leak on module unload
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.
