Actually it's just defined there but not getting used anywhere. In fact
we can remove it from there also. So I submitted another patch to
cleanup such redundant register definitions from plat/map-s5p.h.
Only platform using S3C_UART_OFFSET is s3c64xx and its using definition
from map-s3c.h. I have compiled all related platform defconfigs and
found no issues because of removal of S3C_UART_OFFSET from map-s5p.c and
map.h.
