spi: spi-omap2-mcspi.c: revert "Toggle CS after each word"
Commit 5cbc7ca987 ("spi: spi-omap2-mcspi.c: Toggle CS after each
word") introduced the toggling of CS after each word for the omap2-mcspi
controller.

The implementation is not respectful of the actual spi_message
content, so the CS can be raised after each word even if the
transfer structure asks to keep the CS active for the whole operation.

As it is not used anyway in the current Linux tree, it can be safely
removed.
