spi: s3c drivers shouldn't care about spi_board_info
The two S3C SPI master drivers got merged without much review, so I just noticed that they're doing something that the SPI core code is responsible for, rather than any adapter driver: they try to register SPI devices. This removes that support from those drivers so they act normally. Interestingly, none of the current boards are affected. So it's a net code shrink with no loss of functionality.
