Subject: [PATCH] dt-bindings: iio: afe: voltage-divider: Add io-channel-cells

Add #io-channel-cells expected by driver. i.e., below is the message
seen in kernel log:
OF: /iio-hwmon: could not get #io-channel-cells for /voltage_divider1

TEST=Run below command & make sure there is no error:
make DT_CHECKER_FLAGS=-m dt_binding_check -j1
