[PATCH 1/2] serial: s3c: Fix build of header without serial_core.h preinclusion

[Mark Brown]

From: Mark Brown <broonie at linaro.org>

serial_s3c.h uses upf_t which is defined in serial_core.h but does not
include that itself meaning that users which include serial_s3c.h by
itself don't build.

Signed-off-by: Mark Brown <broonie at linaro.org>

This is needed together with patch 2 to fix build failures in -next, I
didn't have the time/enthusiasm to isolate the issue.
