This isn't a fix or functional change because the devices with 3 chip selects support reading the number of chip selects from hardware, so the value wouldn't have needed to be set here. However the commit states that the DT could be used to overwrite any HW value, so the full range should be supported. This also avoids confusion for any readers about how many chip selects there are.
