mmc: davinci: Poll status for small size transfers
For small size non-dma sdio transactions, it is sometimes better to poll the mmc host and avoid interrupts altogether. Polling lowers the number of interrupts and context switches. Tests have shown that for small transactions, only a few polling iterations are needed, so this is worth while.
