clk: lan966x: add support for lan969x SoC clock driver

Add support for the lan969x SoC clock driver in the existing lan966x
driver. The lan969x clock controller contains 3 PLLs - cpu_clk, ddr_clk
and sys_clk (same as lan966x) which generates and supplies the clock to
various peripherals within the SoC.
