spi: davinci: enable both activation and deactivation of chip-selects

Browse source

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.
