In the read/write function, set port 2 independently in the 2-port case.
When setting the offset of port registers, the offset between port 1 and
other ports is different, so port 1 is set independently.
Then in the rest of ports, the port 2 between 2-ports case and 4-ports case
is different, so port 2 in 2-ports case is set independently.
Specifically, port 2 in the 2-port case maps to the registers used by
port 3 in the 4-port case.
