dt-bindings:iio:adc:st,stmpe-adc yaml conversion

Conversion from freeform text to yaml.
One oddity in this binding is that, for historical reasons it requires
the node name to be stmpe_adc.  I've put that in the decription field
but I'm not sure if there is a better way to specify this?

description:
This ADC forms part of an ST microelectronics STMPE multifunction device .
The ADC is shared with the STMPE touchscreen. As a result some ADC related
settings are specified in the parent node.
The node name myst be stmpe_adc and should be a child node of the stmpe node
to which it belongs.
properties:
compatible:
const: st,stmpe-adc

----------------
Required properties:
- compatible: "st,stmpe-adc"
Optional properties:
Note that the ADC is shared with the STMPE touchscreen. ADC related settings
have to be done in the mfd.
- st,norequest-mask: bitmask specifying which ADC channels should _not_ be
requestable due to different usage (e.g. touch)
Node name must be stmpe_adc and should be child node of stmpe node to
which it belongs.
Example:
stmpe_adc {
compatible = "st,stmpe-adc";
st,norequest-mask = <0x0F>; /* dont use ADC CH3-0 */
};
