dt-bindings:iio:temperature:melexis,mlx90632 conversion to yaml 

Technically this could have gone in trivial-devices.yaml, but I have
kept it as a separate binding due to the detailed additional description
from the text file.

There are various applications for the Infra Red contactless temperature
sensor and MLX90632 is most suitable for consumer applications where
measured object temperature is in range between -20 to 200 degrees
Celsius with relative error of measurement below 1 degree Celsius in
object temperature range for industrial applications. Since it can
operate and measure ambient temperature in range of -20 to 85 degrees
Celsius it is suitable also for outdoor use.
Be aware that electronics surrounding the sensor can increase ambient
temperature. MLX90632 can be calibrated to reduce the housing effect via
already existing EEPROM parameters.
Since measured object emissivity effects Infra Red energy emitted,
emissivity should be set before requesting the object temperature.

* Melexis MLX90632 contactless Infra Red temperature sensor

There are various applications for the Infra Red contactless temperature sensor
and MLX90632 is most suitable for consumer applications where measured object

of measurement below 1 degree Celsius in object temperature range for
industrial applications. Since it can operate and measure ambient temperature

Be aware that electronics surrounding the sensor can increase ambient
temperature. MLX90632 can be calibrated to reduce the housing effect via
already existing EEPROM parameters.
Since measured object emissivity effects Infra Red energy emitted, emissivity
should be set before requesting the object temperature.
Required properties:
- compatible: should be "melexis,mlx90632"
- reg: the I2C address of the sensor (default 0x3a)
Example:
mlx90632@3a {
compatible = "melexis,mlx90632";
reg = <0x3a>;
};
