clk: st: Support for A9 MUX clocks

Browse Source 
The patch supports the A9-mux clocks used by ClockGenA9

A9-mux clock : Multiplexer inside ClockGenA9. A9 clock can be driven by
either PLL or External clock (with an optional divide-by-2). This is
implemented as 3-parent clock : PLL, Ext-clk OR Ext-clk/2
