Subject: [PATCH v3 3/4] dt: add clock binding doc to primecell bindings

From: Rob Herring <rob.herring@...xeda.com>

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:
 
 - arm,primecell-periphid : Value to override the h/w value with
+- clocks : From common clock binding. First clock is phandle to clock for apb
