spi: davinci: remove non-useful interrupt mode support
The interrupt mode support as it stands is another version of poll mode. Even when interrupt mode is selected, the code tight loops on interrupt status register, rendering it totally useless. A completion variable is initialized, but never used. Remove this fake interrupt mode since users can anyway use poll mode with no functional difference. A usefully implemented interrupt mode support can be added later.
