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

Signed-off-by: Eliav Farber <farbere@amazon.com>

V4 -> V3:
- Remove constraints in free-form text descriptions.

V3 -> V2:
- New patch to introduce "moortec,ts-series" property.

I am not a dt expert, but I wonder if this should be handled
with different "compatible" properties. Sorry if this was already
addressed and I missed it.

Thanks,

It was already addressed in [PATCH v3 14/19] by Philipp.
It is indeed confusing which is why I added a detailed description
to moortec,mr75203.yaml in [PATCH v5 07/21].
Shortly, the driver is for the controller unit (mr75203), while the
"series" is a parameter of the temperature unit (mr74137).
Therefore I added a new TS property and not a different compatible.

Thanks a lot for the clarification.
