powerpc/86xx: Add support for Emerson/Artesyn MVME7100 



Add support for the Artesyn MVME7100 Single Board Computer.

The MVME7100 is a 6U form factor VME64 computer with:

    - A two e600 cores Freescale MPC8641D CPU
    - 2 GB of DDR2 onboard memory
    - Four Gigabit Ethernets
    - Five 16550 compatible UARTs
    - One USB 2.0 port
    - Two PCI/PCI eXpress Mezzanine Card (PMC/XMC) Slots
    - A DS1375 Real Time Clock (RTC)
    - 512 KB of Non-Volatile Memory (NVRAM)
    - Two 64 KB EEPROMs
    - 128 MB NOR and 4/8 GB NAND Flash

This patch is based on linux-4.7-rc1 and has been only boot tested.

Limitations:
    This patch covers only models 171 and 173
    No plans to support CPLD timers

Know issues:
    All four PHYs work in polling mode

Configuration is missing for:
    PCI IDSEL and PCI Interrupt definition

Support is missing for:
    Cache and memory controllers (which are very similar to the 85xx ones
        but right now I don't know if we can re-use their support)
    Watchdog, USB, NVRAM, NOR, NAND, EEPROMs, VME, PMC/XMC and RTC
