There are no longer any platforms that use Marvell's mv64x60
hostbridges so remove the supporting kernel code.

-Marvell Discovery mv64[345]6x System Controller chips
-===========================================================
-
-The Marvell mv64[345]60 series of system controller chips contain
-many of the peripherals needed to implement a complete computer
-system.  In this section, we define device tree nodes to describe
-the system controller chip itself and each of the peripherals
-which it contains.  Compatible string values for each node are
-prefixed with the string "marvell,", for Marvell Technology Group Ltd.
-
-1) The /system-controller node
-
-  This node is used to represent the system-controller and must be
-  present when the system uses a system controller chip. The top-level
-  system-controller node contains information that is global to all
-  devices within the system controller chip. The node name begins
-  with "system-controller" followed by the unit address, which is
-  the base address of the memory-mapped register set for the system
-  controller chip.
-
-  Required properties:
-
-    - ranges : Describes the translation of system controller addresses
-      for memory mapped registers.
-    - clock-frequency: Contains the main clock frequency for the system
-      controller chip.
-    - reg : This property defines the address and size of the
-      memory-mapped registers contained within the system controller
-      chip.  The address specified in the "reg" property should match
-      the unit address of the system-controller node.
-    - #address-cells : Address representation for system controller
-      devices.  This field represents the number of cells needed to
-      represent the address of the memory-mapped registers of devices
-      within the system controller chip.
-    - #size-cells : Size representation for the memory-mapped
-      registers within the system controller chip.
-    - #interrupt-cells : Defines the width of cells used to represent
-      interrupts.
-
-  Optional properties:
-
-    - model : The specific model of the system controller chip.  Such
-      as, "mv64360", "mv64460", or "mv64560".
-    - compatible : A string identifying the compatibility identifiers
-      of the system controller chip.
-
-  The system-controller node contains child nodes for each system
-  controller device that the platform uses.  Nodes should not be created
-  for devices which exist on the system controller chip but are not used
-
-  Example Marvell Discovery mv64360 system-controller node:
-
-    system-controller at f1000000 { /* Marvell Discovery mv64360 */
-	    #address-cells = <1>;
-	    #size-cells = <1>;
-	    model = "mv64360";                      /* Default */
-	    compatible = "marvell,mv64360";
-	    clock-frequency = <133333333>;
-	    reg = <0xf1000000 0x10000>;
-	    virtual-reg = <0xf1000000>;
-	    ranges = <0x88000000 0x88000000 0x1000000 /* PCI 0 I/O Space */
-		    0x80000000 0x80000000 0x8000000 /* PCI 0 MEM Space */
-		    0xa0000000 0xa0000000 0x4000000 /* User FLASH */
-		    0x00000000 0xf1000000 0x0010000 /* Bridge's regs */
-		    0xf2000000 0xf2000000 0x0040000>;/* Integrated SRAM */
-
-	    [ child node definitions... ]
-    }
-
-2) Child nodes of /system-controller
-
-   a) Marvell Discovery MDIO bus
-
-   The MDIO is a bus to which the PHY devices are connected.  For each
-   device that exists on this bus, a child node should be created.  See
-   the definition of the PHY node below for an example of how to define
-   a PHY.
-
-   Required properties:
-     - #address-cells : Should be <1>
-     - #size-cells : Should be <0>
-     - compatible : Should be "marvell,mv64360-mdio"

-
-     mdio {

-
-	     ethernet-phy at 0 {
-		     ......
-	     };
-     };
-
-
-   b) Marvell Discovery ethernet controller
-
-   The Discover ethernet controller is described with two levels
-   of nodes.  The first level describes an ethernet silicon block
-   and the second level describes up to 3 ethernet nodes within
-   that block.  The reason for the multiple levels is that the
-   registers for the node are interleaved within a single set
-   of registers.  The "ethernet-block" level describes the
-   shared register set, and the "ethernet" nodes describe ethernet
-   port-specific properties.
