Change all time conversions. Yech. New timer units in microseconds breaks all existing logic that used milliseconds in the conversions.

SAMA5 HSMCI: e-enable TX DMA and verify that DMA writes to the SD card are functional. They are so now TX DMA is re-enabled in the driver. This might affect the SAMA5D3 platforms where the TX DMA problem was found. The SAMA4D3 and 4 use the same HSMCI driver. Much has change since then and it is not surprising that DMA is now functional. However, the has not be re-verified on the SAMA5D3 which has a different DMA controller.
