ARM: s3c64xx: use common debug-ll implementation
The uart on s3c64xx is essentially the same as on s3c24xx, so we can share a single assembler file. However, the addresses are different, and we need to add the respective Kconfig magic to get the right addresses. Signed-off-by: Arnd Bergmann <arnd@arndb.de>
