Heiko Stübner 90c5902540 clk: rockchip: add clock type for pll clocks and pll used on rk3066
All known Rockchip SoCs down to the RK28xx (ARM9) use a similar pattern to
handle their plls:
                       |--\
xin32k ----------------|mux\
xin24m -----| pll |----|pll|--- pll output
       \---------------|src/
                       |--/

The pll output is sourced from 1 of 3 sources, the actual pll being one of
them. To change the pll frequency it is imperative to remux it to another
source beforehand. This is done by adding a clock-listener to the pll that
handles the remuxing before and after the rate change.

The output mux is implemented as a separate clock to make use of already
existing common-clock features for disabling the pll if one of the other
two sources is used.
