Subject: [PATCH] dt-bindings: clock: Convert marvell,dove-divider-clock to DT schema

Convert the Marvell Dove PLL divider clock binding to DT schema format.
It's a straight forward conversion.

-PLL divider based Dove clocks
-
-Marvell Dove has a 2GHz PLL, which feeds into a set of dividers to provide
-high speed clocks for a number of peripherals.  These dividers are part of
-the PMU, and thus this node should be a child of the PMU node.
-
-The following clocks are provided:
-
-ID	Clock
--------------
-0	AXI bus clock
-1	GPU clock
-2	VMeta clock
-3	LCD clock
-
-Required properties:
-- compatible : shall be "marvell,dove-divider-clock"
-- reg : shall be the register address of the Core PLL and Clock Divider
-   Control 0 register.  This will cover that register, as well as the
-   Core PLL and Clock Divider Control 1 register.  Thus, it will have
-   a size of 8.
-- #clock-cells : from common clock binding; shall be set to 1
-
-divider_clk: core-clock@64 {
-	compatible = "marvell,dove-divider-clock";
-	reg = <0x0064 0x8>;
-	#clock-cells = <1>;
