dt-bindings: hwmon: (mr75203) add "moortec,ts-series" property

Add optional "moortec,ts-series" property to define the temperature
equation and coefficients that shall be used to convert the digital
output to value in milli-Celsius.
Supported series: 5 (default) and 6.

Series 5:
  T = G + H * (n / cal5 - 0.5) + J * F
Where: G = 60, H = 200, cal5 = 4094, J = -0.1, F = frequency clock in MHz

Series 6:
   T = G + H * (n / cal5 - 0.5)
Where: G = 57.4, H = 249.4, cal5 = 4096
