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.

-Freescale Localbus UPM programmed to work with NAND flash
-
-Required properties:
-- compatible : "fsl,upm-nand".
-- reg : should specify localbus chip select and size used for the chip.
-- fsl,upm-addr-offset : UPM pattern offset for the address latch.
-- fsl,upm-cmd-offset : UPM pattern offset for the command latch.
-
-Optional properties:
-- fsl,upm-wait-flags : add chip-dependent short delays after running the
-	UPM pattern (0x1), after writing a data byte (0x2) or after
-	writing out a buffer (0x4).
-- fsl,upm-addr-line-cs-offsets : address offsets for multi-chip support.
-	The corresponding address lines are used to select the chip.
-- gpios : may specify optional GPIOs connected to the Ready-Not-Busy pins
-	(R/B#). For multi-chip devices, "n" GPIO definitions are required
-	according to the number of chips.
-- chip-delay : chip dependent delay for transfering data from array to
-	read registers (tR). Required if property "gpios" is not used
-	(R/B# pins not connected).
-
-Examples:
-

-	compatible = "fsl,upm-nand";
-	reg = <1 0 1>;
-	fsl,upm-addr-offset = <16>;
