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.
