Move the common/serial.c into driver/serial/, since this file
provides serial multiplexing functions and it is imperative to
be linked with libserial.o instead of libcommon.o.

If case the get_current() call fails before relocation, the U-Boot
must try to print an error message, fail and either reset or halt.
Such error is critical enough to halt the system, as it means the
system is in very bad state.

This is now also used in SPL, since CONFIG_SERIAL_MULTI is enabled
unconditionally. To avoid compiling whole vsprintf.c into SPL, use
puts() to print error message and hang() to stop the system in case
of SPL build.
