gpio: 104-idi-48: 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-IDI-48.
This should make it easier for users to identify which GPIO line
corresponds to a respective GPIO pin on the device.
