Subject: [PATCH] tty/module.c: include proper header for INIT_C_CC definition

In upstream commit c9874d3ffeaf (termios: start unifying non-UAPI
parts of asm/termios.h), the INIT_C_CC definition was moved to a new
header, termios_internal.h. So we must include that header to get that
macro, but conditionally, since the header does not exist in older
kernels.
