gpio: 104-idio-16: Add support for GPIO names
This patch sets the gpio_chip names option with an array of GPIO line names that match the manual documentation for the ACCES 104-IDIO-16. This should make it easier for users to identify which GPIO line corresponds to a respective GPIO pin on the device.
