dt-bindings: firmware: google,gs101-acpm-ipc: add ACPM clocks
The firmware exposes clocks that can be controlled via the
Alive Clock and Power Manager (ACPM) interface.
Make the ACPM node a clock provider by adding the mandatory
"#clock-cells" property, which allows devices to reference its
clock outputs.
