Subject: [PATCH] dt-bindings: clock: ti,clockdomain: Convert to DT schema

Convert TI clockdomain to yaml DT schema. Drop '#clock-cells' from the
required list as this binding doesn't define a new clock binding type,
it is used to group existing clock nodes under hardware hierarchy. Most
existing dts omit '#clock-cells'.

Update the reference to the old legacy text binding in the description
of bindings/clock/ti/ti,gate-clock.yaml to point to the new YAML file.

-Binding for Texas Instruments clockdomain.
-
-This binding uses the common clock binding[1] in consumer role.
-Every clock on TI SoC belongs to one clockdomain, but software
-only needs this information for specific clocks which require
-their parent clockdomain to be controlled when the clock is
-enabled/disabled. This binding doesn't define a new clock
-binding type, it is used to group existing clock nodes under
