spi: davinci: Remove chip select GPIO pdata
The DaVinci SPI can use either:
- Internal chip selects (inside the SPI host)
- External chip selects (using GPIO)
- External chip selects passed in pdata
The last way of passing external chip selects through
platform data is not used in the kernel. Delete it to make
the code simpler when refactoring GPIO.
