As the MCP23017 has 3 address pins, you are restricted to 8 devices on an I2C bus.
To use more devices you have to open further I2C busses.
Therefore you can use overlays to enable bit banging I2C busses on the Raspberry Pi connector, up to I2C6.

Let's imagine a setup with:
1. a wall switch connected to pin B1 on the MCP23017 chip which should turn on/off your LED light when pressed (released).
2. a relay which is connected to pin A0 on the MCP23017 chip. This relay takes care of turning on/off your light.
1. a relay which is connected to pin A0 on the MCP23017 chip. This relay takes care of turning on/off your light.
Pressing (and releasing) a wall switch should notify openHAB, and then openHAB should change state of relay to on/off the light.
Your pin B1 should work as DIGITAL_INPUT, because it READS state of a PIN (state of wall switch). Your pin A0 should work as DIGITAL_OUTPUT
because openHAB will SET state of this PIN. So your config should look like this:
