[U-Boot] [PATCH v4 03/13] vsprintf: Include stdarg for va_list

[Maxime Ripard]

vsprintf.h doesn't include the stdarg.h file, which means that it relies on
the files that include vsprintf.h to include stdarg.h as well.

Add an explicit include to avoid build errors when simply including that
file.
