serial: nulldev: Add nulldev serial driver
Some device the serial console's initialization cannot run early during the boot process. Hence, nulldev serial device is helpful on that situation. For example, if the serial module was implemented in FPGA. Serial initialization is prohibited to run until the FPGA was programmed. This commit is to adding nulldev serial driver. This will allows the default console to be specified as a nulldev.
