Add a device tree binding for the QIXIS FPGA based GPIO controller. Depending on the board, the QIXIS FPGA exposes registers which act as a GPIO controller, each with 8 GPIO lines of fixed direction. Since each QIXIS FPGA layout has its particularities, add a separate compatible string for each board/GPIO register combination supported. Since these GPIO controllers are trivial, make use of the newly added trivial-gpio.yaml file instead of creating an entirely new one.
