Ludovic Desroches 66b512eda7 mmc: atmel-mci: fix timeout errors in SDIO mode when using DMA
With some SDIO devices, timeout errors can happen when reading data.
To solve this issue, the DMA transfer has to be activated before sending
the command to the device. This order is incorrect in PDC mode. So we
have to take care if we are using DMA or PDC to know when to send the
MMC command.
