The previous change by Kumar Gala in this area led to legacy_serial.c and udbg_16550.c being built as modules when CONFIG_SERIAL_8250=m. Fix this by introducing a new symbol, CONFIG_PPC_UDBG_16550, to control whether these files get built, and arrange for it to be selected for those platforms that need it.
