[PATCH 02/13] dt-bindings: trivial-devices: Add mcp342x ADCs and drop separate binding doc.

[Jonathan Cameron <jic23@kernel.org>]

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

These i2c devices have simple bindings, well described by trivial-device.yaml
so rather than convert the binding doc to yaml, let us just add them to
trivial devices and drop the old binding document.
