spi: davinci: enable both activation and deactivation of chip-selects
Let davinci_spi_chipselect() perform both activation and deactivation of chip selects. This lets spi_bitbang fully control chip select activation, as intended by the SPI API. With this change, the chip select activation code need not be duplicated in davinci_spi_bufs_{pio|dma}(). Also, keeping chip select active control is removed as a platform data and simply controlled using information from spi_bitbang on whether chip slect should be activated or de-activated.
