clk: wm831x: Add initial WM831x clock driver The WM831x and WM832x series of PMICs contain a flexible clocking subsystem intended to provide always on and system core clocks. It features: - A 32.768kHz crystal oscillator which can optionally be used to pass through an externally generated clock. - A FLL which can be clocked from either the 32.768kHz oscillator or the CLKIN pin. - A CLKOUT pin which can bring out either the oscillator or the FLL output. - The 32.768kHz clock can also optionally be brought out on the GPIO pins of the device. This driver fully supports the 32.768kHz oscillator and CLKOUT. The FLL is supported only in AUTO mode, the full flexibility of the FLL cannot currently be used. Due to a lack of access to systems where the core SoC has been converted to use the generic clock API this driver has been compile tested only.
