clk: dts: document pxa clock binding
Document the device-tree binding of Marvell PXA based SoCs. PXA clocks are mostly fixed rate and fixed ratio clocks derived from an external oscillator, and gated by a register set (CKEN or CKEN*).

+* Clock bindings for Marvell PXA chips
+Required properties:
+- compatible: Should be "marvell,pxa-clocks"
+- #clock-cells: Should be <1>
+The clock consumer should specify the desired clock by having the clock
+ID in its "clocks" phandle cell (see include/.../pxa-clock.h).
