[PATCH linux dev-4.10 1/6] dt-bindings: max31785: Add mark-fan-installed property

[Andrew Jeffery]

It's a system design decision with regards to managing the default
values of registers such as FAN_CONFIG_1_2. Do not assume the hardware
is configured such as the fans are marked as installed, rather expose a
devicetree option to inform the driver of whether it should mark the
fan as installed itself.
