fix(dcc): add dcc console unregister function
Add unregistration function for the JTAG DCC (Debug Communication
Channel) console.
The unregistration function flushes DCC buffer before unregistering
the dcc console to make sure that no output char is pending.
Since console_flush() flushes chars for all registered consoles on
the platform, which is not required in this case, dcc_console_flush()
is being called instead.
