Tero Kristo f19de1bc67 crypto: omap-sham - add support functions for sg based data handling 
Currently omap-sham uses a huge internal buffer for caching data, and
pushing this out to the DMA as large chunks. This, unfortunately,
doesn't work too well with the export/import functionality required
for ahash algorithms, and must be changed towards more scatterlist
centric approach.

This patch adds support functions for (mostly) scatterlist based data
handling. omap_sham_prepare_request() prepares a scatterlist for DMA
transfer to SHA crypto accelerator. This requires checking the data /
offset / length alignment of the data, splitting the data to SHA block
size granularity, and adding any remaining data back to the buffer.
With this patch, the code doesn't actually go live yet, the support code
will be taken properly into use with additional patches that modify the
SHA driver functionality itself.
