Ben Dooks b6d1f542e3 [ARM] 4049/1: S3C24XX: fix sparse warning due to upf_t in regs-serial.h
Change the include/asm-arm/arch-s3c2410/regs-serial.h
platform data to use the prorper type (upf_t) for the
uart_flags.

Fix all the other parts of arch/arm/mach-s3c2410 to
include <linux/serial_core.h> and all other uses of
the include file.

mach-rx3715.c:101:18: warning: incorrect type in initializer (different base types)
mach-rx3715.c:101:18:    expected unsigned long [unsigned] uart_flags
mach-rx3715.c:101:18:    got restricted unsigned int [usertype] [force] <noident>
