dt: Move device tree documentation out of powerpc directory

The device tree is used by more than just PowerPC.  Make the documentation
directory available to all.

v2: reorganized files while moving to create arch and driver specific
    directories.

-fsl,mpc5200-mscan nodes
------------------------
-In addition to the required compatible-, reg- and interrupt-properties, you can
-also specify which clock source shall be used for the controller:
-
-- fsl,mscan-clock-source : a string describing the clock source. Valid values
-			   are:	"ip" for ip bus clock
-				 "ref" for reference clock (XTAL)
-			   "ref" is default in case this property is not
-			   present.
-
-fsl,mpc5121-mscan nodes
------------------------
-In addition to the required compatible-, reg- and interrupt-properties, you can
-also specify which clock source and divider shall be used for the controller:
-
-- fsl,mscan-clock-source : a string describing the clock source. Valid values
-			   are:	"ip" for ip bus clock
-				"ref" for reference clock
-				"sys" for system clock
-			   If this property is not present, an optimal CAN
-			   clock source and frequency based on the system
-			   clock will be selected. If this is not possible,
-			   the reference clock will be used.
-
-- fsl,mscan-clock-divider: for the reference and system clock, an additional
-			   clock divider can be specified. By default, a
-			   value of 1 is used.
-
-Note that the MPC5121 Rev. 1 processor is not supported.

-Examples:
-	can@1300 {
-		compatible = "fsl,mpc5121-mscan";
-		interrupts = <12 0x8>;
-		interrupt-parent = <&ipic>;
-		reg = <0x1300 0x80>;
-	};
-
-	can@1380 {
-		compatible = "fsl,mpc5121-mscan";
-		interrupts = <13 0x8>;
-		interrupt-parent = <&ipic>;
-		reg = <0x1380 0x80>;
-		fsl,mscan-clock-source = "ref";
-		fsl,mscan-clock-divider = <3>;
-	};
