CONFIG_ARM_DCC_MULTI should be also removed in the patch "serial: Remove CONFIG_SERIAL_MULTI from serial drivers" (sha1: a3827250606895ec2dd4b8d867342b7cabf3692f) Because the driver defines serial_* functions which cause conflict with serial.c (multiple definition of serial_*)
Removing CONFIG_SERIAL_MULTI function also require to define default_serial_console for cases where another serial driver is not available in the system.
