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@0064 {
	compatible = "marvell,dove-divider-clock";
	reg = <0x0064 0x8>;
	#clock-cells = <1>;
};
