mmc: adma: Ensure the adma descriptor table reaches main maemory.ti-2.6.33-rc2-omap4-L24.4-p4
The current MMC driver uses adam for it's data transfer. The decsriptor
table memory is non-cached but it can still reside in the buffers.
Add a necessary write memory barrier so that DMA controller sees the
correct descriptor.
