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 MSI interrupt controller
-
-Required properties:
-- compatible : compatible list, contains 2 entries,
-  first is "fsl,CHIP-msi", where CHIP is the processor(mpc8610, mpc8572,
-  etc.) and the second is "fsl,mpic-msi" or "fsl,ipic-msi" depending on
-  the parent type.
-- reg : should contain the address and the length of the shared message
-  interrupt register set.
-- msi-available-ranges: use <start count> style section to define which
-  msi interrupt can be used in the 256 msi interrupts. This property is
-  optional, without this, all the 256 MSI interrupts can be used.
-- interrupts : each one of the interrupts here is one entry per 32 MSIs,
-  and routed to the host interrupt controller. the interrupts should
-  be set as edge sensitive.
-- interrupt-parent: the phandle for the interrupt controller
-  that services interrupts for this device. for 83xx cpu, the interrupts
-  are routed to IPIC, and for 85xx/86xx cpu the interrupts are routed
-  to MPIC.

-Example:
-        msi@41600 {
-                compatible = "fsl,mpc8610-msi", "fsl,mpic-msi";
-                reg = <0x41600 0x80>;
-                msi-available-ranges = <0 0x100>;
-                interrupts = <
-                        0xe0 0
-                        0xe1 0
-                        0xe2 0
-                        0xe3 0
-                        0xe4 0
-                        0xe5 0
-                        0xe6 0
-                        0xe7 0>;
-                interrupt-parent = <&mpic>;
-        };
