Subject: [PATCH v4 0/2] hwmon/tmp401: add support of three advanced features

According the their datasheets:
- TMP401, TMP411 and TMP43x support extended temperature range;
- TMP411 and TMP43x support n-factor correction;
- TMP43x support beta compensation.

In order to make it possible for users to enable these features and set up them
based on their needs, this patch series adds the following devicetree bindings:
- ti,extended-range-enable;
- ti,n-factor;
- ti,beta-compensation.
In the meanwhile, tmp401 driver reads them and configures the coressponding
registers accordingly.

v4:
- just add reviewed-by, no change on code.

v3:
- dt-bindings: remove unused [address|size]_cells and ti,beta-compensation.items
  from ti,tmp401.yaml;
- dt-bindings: change ti,n-factor range to [-128, 127];
- tmp401.c: instead of u32, use s32 for ti,n-factor.

v2:
- dt-bindings: fix format and describe hardware properties instead of
  programming models in ti,tmp401.yaml.
