dt-bindings: hwmon: (mr75203) add coefficient properties for the thermal equation
Add optional temperature coefficient properties:
*) moortec,ts-coeff-g
*) moortec,ts-coeff-h
*) moortec,ts-coeff-cal5
*) moortec,ts-coeff-j
If defined they shall be used instead of defaults.
The coefficients were added to device tree on top of the series property
(which can be used to select between series 5 and series 6), because
coefficients can vary between product and product, and code defaults might
not be accurate enough.
