[PATCH 3/8] crypto4xx_core: don't abuse __dma_sync_page

[Christoph Hellwig <hch@lst.de>]

This function is internal to the DMA API implementation.  Instead use the
DMA API to properly unmap.  Note that the DMA API usage in this driver
is a disaster and urgently needs some work - it is missing all the unmaps,
seems to do a secondary map where it looks like it should to a unmap
in one place to work around cache coherency and the directions passed in
seem to be partially wrong.
