For split keyboards using `LED_MATRIX_SPLIT` with an LED driver, you can either have the same driver address or different driver addresses. If using different addresses, use `DRIVER_ADDR_1` for one and `DRIVER_ADDR_2` for the other one. Then, in `g_is31_leds`, fill out the correct driver index (0 or 1). If using one address, use `DRIVER_ADDR_1` for both, and use index 0 for `g_is31_leds`.
