[PATCH 3/6] P2020DS: Fixup sdhc to use PIO mode

[Gao Guanhua-B22826]

Hi, Kumar,

I tried to update the patch based on the latest kernel tree
(2.6.32-rc6), there are some problems:
1) the P2020DS board has supported SDHC using DMA, and the latest kernel
tree has included the related code, it doesn't need most of the patches
I posted before.
2) I compiled the image, but the SDHC can not work, it reports error
-110. I adjusted the timeout to the max value, but anther error
occurred.
