Few coefficients use default values multiple of 100, not 1000 (in the
example DTS and in the Linux driver):

 moortec,mr75203.example.dtb: pvt@e0680000: moortec,ts-coeff-g:0:0: 61400 is not a multiple of 1000

Why isn't multiple of 1000 correct?
According to the Moortec datasheet for the series 6 of the temperature sensor
the coefficients are:
G = 57.4 (57.4 * 1000 = 57400)
H = 249.4
For series 5 coefficients are:
G = 60 (60 * 1000 = 60000)
H = 200
J = -0.1
