dt-bindings: pinctrl: mcp23s08: Clarify gpiospec flags cell usage The pinctrl-mcp23s08 driver doesn't provide a specific gpiospec of_xlate() function, causing the gpiolib-of's of_gpio_simple_xlate() function to be used instead, which takes the gpiospec's second cell as the flags specifier according to 'include/dt-bindings/gpio/gpio.h'. The pinctrl-mcp23s08 bindings document was mentioning that the flags were unused, which is not accurate because values in that second cell are indeed used by the gpiolib-of's of_gpio_simple_xlate() for configuring the gpio (e.g. its polarity). This way, replace the "flags currently unused" reference in the dt-bindings document with references to the appropriate files specifying the possible flag values and gpiospec description.
