[PATCH v2 1/2] dt-bindings: hwmon: moortec,mr75203: adapt multipleOf for T-Head TH1520

The G and J coefficients provided by T-Head TH1520 manual (which calls
them A and C coefficients and calls H coefficient in the binding as B)
has the 1/100 degree Celsius bit (the values are 42.74 and -0.16
correspondingly), however the binding currently only allows cofficients
as precise as 100 milli-Celsius (1/10 degree Celsius).

Change the multipleOf value of these two cofficients to 10 (in the unit
of milli-Celsius) to satisfy the need of TH1520.
