From: Brian Niebuhr <bnieb...@efjohnson.com>
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.
