[PATCH 2/2] dt-bindings: clock: intel,cgu-lgm: add mxl,control-gate option

[Florian Eckert <fe@dev.tdt.de>]

Add the new option 'mxl,control-gate'. Gate clocks can be controlled
either from this cgu clk driver or directly from power management
driver/daemon. It is dependent on the power policy/profile requirements
of the end product. To take control of gate clks from this driver, add the
name of the gate to this <mxl,control-gate> devicetree property.
Please refer to 'drivers/clk/x86/clk-lgm.c' source file for the gate names.
