[U-Boot-Users] [PATCH RESEND] serial: Make default_serial_console() a weak function

[Matthias Fuchs]

With this patch it is possible to reimplement default_serial_console()
in board specific code. This will be done in the upcomming PMC440
U-Boot port. This also allows the lwmon board maintainer to
remove the '#if !defined(CONFIG_LWMON) ...' from common/serial.c.
