Subject: [PATCH] spi: Add documentation for last_cs_index_mask

Documentation was missing for last_cs_index_mask, this was shown by
a warning in make htmldocs.

I have based the documentation off the docs for cs_index_mask, given
that they should be similar.

This is my first patch, so I hope I did everything right, please let
me know if I need to change something, and I shall endevour to do it
properly.
