iio: adc: ad7606: fix standby gpio state to match the documentation
[ Upstream commit 059fe4f8bbdf5cad212e1aeeb3e8968c80b9ff3b ]
The binding's documentation specifies that "As the line is active low, it
should be marked GPIO_ACTIVE_LOW". However, in the driver, it was handled
the opposite way. This commit sets the driver's behaviour in sync with the
documentation
