powerpc: Remove Xilinx PPC405/PPC440 support

The latest Xilinx design tools called ISE and EDK has been released in
October 2013. New tool doesn't support any PPC405/PPC440 new designs.
These platforms are no longer supported and tested.

PowerPC 405/440 port is orphan from 2013 by
commit cdeb89943bfc ("MAINTAINERS: Fix incorrect status tag") and
commit 19624236cce1 ("MAINTAINERS: Update Grant's email address and maintainership")
that's why it is time to remove the support fot these platforms.

-   Some IP cores actually implement 2 or more logical devices.  In
-   this case, the device should still describe the whole IP core with
-   a single node and add a child node for each logical device.  The
-   ranges property can be used to translate from parent IP-core to the
-   registers of each device.  In addition, the parent node should be
-   compatible with the bus type 'xlnx,compound', and should contain
-   #address-cells and #size-cells, as with any other bus.  (Note: this
-   makes the assumption that both logical devices have the same bus
-   binding.  If this is not true, then separate nodes should be used
-   for each logical device).  The 'cell-index' property can be used to
-   enumerate logical devices within an IP core.  For example, the
-   following is the system.mhs entry for the dual ps2 controller found
-   on the ml403 reference design.
-
-	BEGIN opb_ps2_dual_ref
-		PARAMETER INSTANCE = opb_ps2_dual_ref_0
-		PARAMETER HW_VER = 1.00.a
-		PARAMETER C_BASEADDR = 0xA9000000
-		PARAMETER C_HIGHADDR = 0xA9001FFF

-		PORT Clkin1 = ps2_clk_rx_1

-		PORT Rx2 = ps2_d_rx_2
-		PORT Txpd1 = ps2_d_tx_1
-		PORT Txpd2 = ps2_d_tx_2
-	END
-
-   It would result in the following device tree nodes:
-
-	opb_ps2_dual_ref_0: opb-ps2-dual-ref@a9000000 {
-		#address-cells = <1>;
-		#size-cells = <1>;
-		compatible = "xlnx,compound";
-		ranges = <0 a9000000 2000>;
-		// If this device had extra parameters, then they would
-		// go here.
-		ps2@0 {
-			compatible = "xlnx,opb-ps2-dual-ref-1.00.a";
-			reg = <0 40>;
-			interrupt-parent = <&opb_intc_0>;

-		};

-   Also, the system.mhs file defines bus attachments from the processor
-   to the devices.  The device tree structure should reflect the bus
-   attachments.  Again an example; this system.mhs fragment:
