Add support for the Freescale P5040DS Reference Board ("Superhydra"), which
is similar to the P5020DS.  Features of the P5040 are listed below, but
not all of these features (e.g. DPAA networking) are currently supported.

Four P5040 single-threaded e5500 cores built
    Up to 2.4 GHz with 64-bit ISA support
    Three levels of instruction: user, supervisor, hypervisor
CoreNet platform cache (CPC)
    2.0 MB configures as dual 1 MB blocks hierarchical interconnect fabric
Two 64-bit DDR3/3L SDRAM memory controllers with ECC and interleaving
 support Up to 1600MT/s
    Memory pre-fetch engine
DPAA incorporating acceleration for the following functions
    Packet parsing, classification, and distribution (FMAN)
    Queue management for scheduling, packet sequencing and
	congestion management (QMAN)
    Hardware buffer management for buffer allocation and
	de-allocation (BMAN)
    Cryptography acceleration (SEC 5.0) at up to 40 Gbps SerDes
    20 lanes at up to 5 Gbps
    Supports SGMII, XAUI, PCIe rev1.1/2.0, SATA Ethernet interfaces
    Two 10 Gbps Ethernet MACs
    Ten 1 Gbps Ethernet MACs
High-speed peripheral interfaces
    Two PCI Express 2.0/3.0 controllers
Additional peripheral interfaces
    Two serial ATA (SATA 2.0) controllers
    Two high-speed USB 2.0 controllers with integrated PHY
    Enhanced secure digital host controller (SD/MMC/eMMC)
    Enhanced serial peripheral interface (eSPI)
    Two I2C controllers
    Four UARTs
    Integrated flash controller supporting NAND and NOR flash
DMA
    Dual four channel
Support for hardware virtualization and partitioning enforcement
    Extra privileged level for hypervisor support
QorIQ Trust Architecture 1.1
    Secure boot, secure debug, tamper detection, volatile key storage

The Freescale hypervisor does not allow guests to write to the timebase
registers (virtualizing the timebase register was deemed too complicated),
so don't try to synchronize the timebase registers when we're running
under the hypervisor.

This typically happens when kexec support is enabled.

e500mc cannot doze or nap due to an erratum (as well as having a
different mechanism than previous e500), but it has a "wait" instruction
that is similar to doze.

On 64-bit, due to the soft-irq-disable mechanism, the existing
book3e_idle should be used instead.

Add support for the ePAPR-compliant Freescale hypervisor (aka "Topaz") on
the Freescale P3041DS, P4080DS, and P5020DS reference boards.

The P5020DS is in the same family of boards as the P4080 DS and thus
shares the corenet_ds code.

Add basic support for the P4080 DS reference board.  None of the data
path devices (ethernet, crypto, pme) are support at this time.
