a44a23ed4d powerpc/85xx: Stop using ppc_md.init on socrates
Match what other 85xx platforms do for of_platform_bus_probe and use
machine_device_initcall.  This is one small step in killing of
ppc_md.init.

393adcacad powerpc/85xx: Add support for the "socrates" board (MPC8544).
Supported are Ethernet, serial console, I2C, I2C-based RTC and
temperature sensors, NOR and NAND flash, PCI, USB, CAN and Lime
display controller.

The multiplexing of FPGA interrupts onto PowerPC interrupt lines is
supported through our own fpga_pic interrupt controller driver.

For example the SJA1000 controller is level low sensitive connected to
fpga_pic line 2 and is routed to the second (of three) irq lines to
the CPU:

    can@3,100 {
            compatible = "philips,sja1000";
            reg = <3 0x100 0x80>;
            interrupts = <2 2>;
            interrupts = <2 8 1>;   // number, type, routing
            interrupt-parent = <&fpga_pic>;
    };
