AMS Sansa: Remove MCI_RX_ACTIVE FIFO check following SD transfers.

Browse source 
We don't need to check the FIFO for MCI_RX_ACTIVE because we don't experience problems reading from the SD cards.
We need the MCI_TX_ACTIVE FIFO check during writes because some SD cards spend longer times in the PRG state
programming the data that has been written to them.
