spi: davinci: enable GPIO lines to be used as chip selects

Sometimes, the chip selects provided by SPI module are
muxed with other functionality and cannot be used in
some designs. In such cases, it becomes convenient to use
an available GPIO line as chip select.

This patch enables the DaVinci SPI driver to treat specific
GPIO lines as chip selects based on information provided in
platform data.
