sh: import missing private libraries from Linux 3.19
SuperH is supposed to support the Private Library feature, but it is
actually not working.
If CONFIG_USE_PRIVATE_LIBGCC is enabled, the build fails for the
undefined references to '__sdivsi3_i4i' and '__udivsi3_i4i'.
To fix this error, import missing libraries from Linux 3.19
and adjust them for U-Boot:
- Remove "#include <linux/module.h>" and "EXPORT_SYMBOL(...)"
- Use SPDX-License-Identifier
- Remove white space
