[PATCH] dt-bindings: hwmon: ti,tmp401: add vcc-supply and #thermal-sensor-cells

[Vincent Jardin via B4 Relay]

From: Vincent Jardin <vjardin@xxxxxxx>

Both properties are used by the driver that backs this binding, and
neither is described, so a board that supplies either fails dtbs_check:

  tmp411@4c (ti,tmp411): '#thermal-sensor-cells', 'vcc-supply' do not
  match any of the regexes: '^pinctrl-[0-9]+$'

vcc-supply is fetched in lm90_probe():

  drivers/hwmon/lm90.c:2777
        err = devm_regulator_get_enable(dev, "vcc");

so a board with the sensor behind a switched rail has no other way to
describe it, and omitting it means the chip is probed with its supply
possibly off.
