i2c: Fix port bug with i2ctrace and i2cscan commands
'port' is not the index into i2c_ports[]. Fix i2ctrace and
i2cscan to use get_i2c_port() to find the matching port in
i2c_ports[] table.
Add the port name to the 'i2ctrace list' output to make it
clear which port it is.
> i2ctrace list
id port address
-- ---- -------
0 8 ap_audio 0x4A
1 9 ap_hdmi 0x5A to 0x5F
2 3 ap_mux 0x30

4 5 sensor 0x50
