ARM: dts: omap24xx: add minimal l4 bus layout with control module support 



This patch creates an l4 / l4-wkup interconnects for omap2420 / omap2430
SoCs, and moves some of the generic peripherals under it. System control
module nodes are moved under this new interconnect also, and the SCM
clock layout is changed to use the new SCM node as the clock provider.

L4 interconnect bindings



These bindings describe the OMAP SoCs L4 interconnect bus.



Required properties:

- compatible : Should be "ti,omap2-l4" for OMAP2 family l4 core bus

	       Should be "ti,omap2-l4-wkup" for OMAP2 family l4 wkup bus

- ranges : contains the IO map range for the bus



Examples:



l4: l4@48000000 {

	compatible "ti,omap2-l4", "simple-bus";

	#address-cells = <1>;

	#size-cells = <1>;

	ranges = <0 0x48000000 0x100000>;

};
