spi: spi_s3c24xx must initialize num_chipselect
The SPI core now expects num_chipselect to be set correctly as due to added
checks on the chip being selected before an transfer is allowed.  This patch
adds a num_cs field to the platform data which needs to be set correctly
before adding the SPI platform device.
