Keng Soon Cheah cac73f20ac 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.
