xtensa: ISS: fix rs_put_char ISS serial console prints garbage instead of symbols printed via rs_put_char. gcc optimizes away putting prined symbol into memory buffer because there's no evidence that the buffer is used afterwards. Make rs_put_char and rs_write use simc_write that has explicit wmb. Signed-off-by: Max Filippov <jcmvbkbc@gmail.com> Signed-off-by: Chris Zankel <chris@zankel.net>
