serial: core: Fix probing serial_base_bus devices
If a physical serial port device driver uses arch_initcall() we fail to
probe the serial_base_bus devices and the serial port tx fails. This is
because as serial_base_bus uses module_initcall().
Let's fix the issue by changing serial_base_bus to use arch_initcall().
Let's also return an error if a driver attempts to call uart_add_one_port()
too early.
