console: Squelch pre-console output in console functions
There are some locations in the code which anticipate printf() being called before the console is ready by squelching printf() on gd->have_console. Move this squelching into printf(), vprintf(), puts() and putc(). Also make tstc() and getc() return 0 if console is not yet initialised Signed-off-by: Graeme Russ <graeme.russ@gmail.com> Tested-by: Simon Glass <sjg@chromium.org>
