[PATCH v2 2/3] clk: bcm2835: Support for clock parent selection

Some bcm2835 clocks used by hardware (like "PWM" or "H264") can have multiple parent clocks. These clocks divide the rate of a parent which can be selected by setting the proper bits in the clock control register. Previously all these parents where handled by a mux clock. But a mux clock cannot be
