ARM: S3C24XX: Add HSSPI setup callback for s3c64xx-spi driver
This lets the s3c64xx-spi driver know the specifics of the controller- variant and also setups the gpios and the misccr bit. This setup is valid for all S3C24XX SoCs containing a HSSPI controller (i.e. S3C2416/2450 and S3C2443) Signed-off-by: Heiko Stuebner <heiko@sntech.de> Signed-off-by: Kukjin Kim <kgene.kim@samsung.com>
