dt: add clock binding doc to primecell bindings
Add clock binding information for primecell peripherals. For most, a clock input name of "apb_pclk" is required. Any primecell peripherals which are different will need to be documented separately.

Optional properties:

+- clocks : From common clock binding. First clock is phandle to clock for apb

+- clock-names : From common clock binding. Shall be "apb_pclk" for first clock.
