The first two patches improve performance on Versatile, from 20.5s to
read 1MB down to 18.5s - a 10% improvement.

I was worried that the first patch would add too much overhead, and
cause the hardware to overrun - as the ARM version of these primecells
does not have the capability to stop the clock when the FIFO fills
up, any increase in IRQ latency to read the FIFO will result in an
overrun.

So this is good news.  I've applied the first three patches in this
series, but we do need to sort out the card detect situation properly
before continuing.
