SPEAr platforms now support DT and so must convert all drivers to support DT.
This patch adds DT probing support for Arasan Compact Flash controller and
updates its documentation too.

* ARASAN PATA COMPACT FLASH CONTROLLER



Required properties:

- compatible: "arasan,cf-spear1340"

- reg: Address range of the CF registers

- interrupt-parent: Should be the phandle for the interrupt controller

  that services interrupts for this device

- interrupt: Should contain the CF interrupt number



Example:



	cf@fc000000 {

		compatible = "arasan,cf-spear1340";

		reg = <0xfc000000 0x1000>;

		interrupt-parent = <&vic1>;

		interrupts = <12>;

	};
