[PATCH 07/10] dt-bindings:iio:adc:maxim,max1027: Pull out to separate binding doc.

[Jonathan Cameron <jic23@kernel.org>]

From: Jonathan Cameron <Jonathan.Cameron@huawei.com>

The afe/voltage-divider.yaml example uses this device with 2 properties
not provided by trivial-devices.yaml (spi-max-frequency and #io-channel-cells)

Solve that by creating a more specific binding doc.
