iio: adc: ti-ads7950: normalize return value of gpio_get
The GPIO get callback is expected to return 0 or 1 (or a negative error
code). Ensure that the value returned by ti_ads7950_get() for output
pins is normalized to the [0, 1] range.
Fixes: 86ef402d805d ("gpiolib: sanitize the return value of gpio_chip::get()")
