The Orange Pi Plus really is an Orange Pi 2 extended with:
1) A sata <-> usb bridge connected to ehci3
2) An eMMC on mmc2
3) An external gigabit ethernet phy instead of the integrated 100Mbit phy

This commit changes the dts to reflect this by making it include
the Orange Pi 2 dts and then adding the extra bits.

Note that the difference in ethernet phy is not taken into account
because we do not have an ethernet driver for the H3 yet.

The Orangepi Plus has a 16GB eMMC, the vcc, the lack of pull-ups and
the use of the hw-reset pin have all been verified with the board
schematic.

With this dts node for mmc2, the eMMC runs at the following ios settings:
clock:          52000000 Hz
vdd:            21 (3.3 ~ 3.4 V)
bus mode:       2 (push-pull)
chip select:    0 (don't care)
power mode:     2 (on)
bus width:      3 (8 bits)
timing spec:    8 (mmc DDR52)
signal voltage: 0 (3.30 V)
driver type:    0 (driver type B)

Note the mmcblk1boot0/boot1 partitions are unused as the BROM will load
the SPL from 8k from the start of the main blockdev, just as with a
regular sdcard in mmc0.

The Orangepi Plus and Orangepi Plus 2 have a realtek rtl8189etv sdio
wifi chip. This commit adds a device-tree node to power it up, so
that the mmc subsys can scan it, and enables the mmc controller which
is connected to it.

Note that this just makes the wifi controller show up as a sdio device.
In order for it to work a compatible sdio driver is necessary, an out
of tree driver is available here:
https://github.com/jwrdegoede/rtl8189ES_linux/

Binding the driver is not done through device tree, but through sdio
vendor- and device-id, so it can safely be enabled in devicetree
without having a driver upstream yet.

Pull orangefs filesystem from Mike Marshall.

This finally merges the long-pending orangefs filesystem, which has been
much cleaned up with input from Al Viro over the last six months.  From
the documentation file:

 "OrangeFS is an LGPL userspace scale-out parallel storage system.  It
  is ideal for large storage problems faced by HPC, BigData, Streaming
  Video, Genomics, Bioinformatics.

  Orangefs, originally called PVFS, was first developed in 1993 by Walt
  Ligon and Eric Blumer as a parallel file system for Parallel Virtual
  Machine (PVM) as part of a NASA grant to study the I/O patterns of
  parallel programs.

  Orangefs features include:

    - Distributes file data among multiple file servers
    - Supports simultaneous access by multiple clients
    - Stores file data and metadata on servers using local file system
      and access methods
    - Userspace implementation is easy to install and maintain
    - Direct MPI support
    - Stateless"
