dt-bindings: thermal: cooling-devices: Update support for 3 cells cooling device
Extend the thermal cooling device binding to support a 3 cells specifier
along with the 2 cells format.
Update #cooling-cells property to enum to support both 2 and 3 arguments.
Fix pwm-fan.yaml to restrict the number of cells to 'const: 2'
