tty: serial/samsung: make register definitions global
The registers for the Samsung S3C serial port are currently defined in the platform specific arch/arm/plat-samsung/include/plat/regs-serial.h file, which is not visible to multiplatform capable drivers. Unfortunately, it is not possible to move the file into a more local place as we should normally try to, because the same registers may be used in one of four places: * In the driver itself * In platform-independent ARM code for early debug output * In platform_data definitions * In the Samsung platform power management code I have also found no way to logically split out a platform_data file, other than possibly move everything into include/linux/platform_data, which also felt wrong. The only part of this file that makes sense to keep specific to the s3c24xx platform are the virtual and physical addresses defined here, which are needed in no other location.
