sunxi: mmc: increase status register polling rate for data transfers
With a recent bunch of SD3.0 cards in our A20-based board we experienced data transfer rates of about 250 KiB/s instead of 10 MiB/s with previous cards from the same vendor (both 4 GB/class 10). By increasing status register polling rate from 1 kHz to 1 MHz we were able to reach the original transfer rates again. With the old cards we now even reach about 16 MiB/s.
