dm: serial: Allow driver-model serial to be disabled for TPL
Add separate enable/disable controls for driver-model serial. While this is generally enabled in SPL it may not be in TPL, since serial output can be obtained with the debug UART with minimal code size. Signed-off-by: Simon Glass <sjg@chromium.org>
