f6a52403fd dt-bindings: iio: mcp9600: Add microchip,mcp9601 and add constraints 
Add microchip,mcp9601 compatible in addition to the original
microchip,mcp9600 to designate support between these two chips.

The current dt-binding has open-circuit and short-circuit as interrupt
names, but these are only supported in mcp9601.

The OC and SC detection requires that mcp9601 VSENSE be wired up, which
not only enables the OC SC interrupts, but also the OC and SC status
register bits.

Add a microchip,vsense boolean to show the chip is wired for this
support.

Add constraints so this feature only applies if the mcp9601 compatible
is selected.

d6d389646a dt-bindings: iio: mcp9600: Set default 3 for thermocouple-type 
As is already documented in this file, Type-K is the default, so make
that explicit in the dt-bindings.
