spi: davinci: remove 'wait_enable' platform data member

Browse source 
The SPI_READY bit of struct spi_device:mode serves the purpose
of letting the SPI master know if the slave can signal if it is
ready for transfer or not.

The 'wait_enable' platform data was duplicating this functionality.
Use the framework provided method of indicating this capability.
