clk: mxl: Add option to override gate clks
In MxL's LGM SoC, gate clocks can be controlled either from CGU clk driver
i.e. this driver or directly from power management driver/daemon. It is
dependent on the power policy/profile requirements of the end product.
To support such use cases, provide option to override gate clks enable/disable
by adding a flag GATE_CLK_HW which controls if these gate clks are controlled
by HW i.e. this driver or overridden in order to allow it to be controlled
by power profiles instead.
