[PATCH v5 1/3] dt-bindings: hwmon: Add Infineon TDA38640

[Naresh Solanki <naresh.solanki@9elements.com>]

From: Patrick Rudolph <patrick.rudolph@9elements.com>

Add the DT property 'infineon,en-pin-fixed-level' to
indicated that the chip EN pin is at fixed level
or left unconnected(has internal pull-down).
