spi: s3c64xx: explicitly include <linux/types.h>

The driver uses u32 and relies on an implicit inclusion of
<linux/types.h>.

It is good practice to directly include all headers used, it avoids
implicit dependencies and spurious breakage if someone rearranges
headers and causes the implicit include to vanish.

Include the missing header.
