dt-bindings: hwmon: Convert aspeed,ast2400-pwm-tacho to DT schema

Browse source

Convert the ASpeed fan controller binding to DT schema format.

The '#size-cells' value is 0 rather 1.

Some users define more that 8 fan nodes where 2 fans share a PWM. The
driver seems to let the 2nd fan just overwrite the 1st one. That also
creates some addressing errors in the DT (duplicate addresses and wrong
unit-addresses).
