[PATCH] fix celleb link failure

[Christoph Hellwig <hch@lst.de>]

txx9_serial_init calls early_serial_txx9_setup which is only available
if CONFIG_SERIAL_TXX9_CONSOLE is define.  From looking at scc_sio.c
it seems like the whole file is only needed for
CONFIG_SERIAL_TXX9_CONSOLE=y, so we should only build it for that case.
