We have for the H3 boards some kind of cargo cult apparently, where we
would have a pinctrl node even for GPIOs without any particular settings.
This is pretty much useless, so let's remove them.

The Orange Pi Plus board lacks voltage scaling capabilities in its
current form. This results in random freezes during boot when cpufreq is
enabled, probably due to wrong voltages.
This patch (more or less copy/paste from 06139c) does the following
things on this board:
- enable r_i2c
- add sy8106a to the r_i2c bus
- have the sy8106a regulate VDD of cpu
Since the Orange Pi Plus has the same PMU setup as the Orange Pi PC, I
simply took min/max/fixed/ramp from the latter DTS. In that file the
origin of the values are described by the following comment:
"The datasheet uses 1.1V as the minimum value of VDD-CPUX,
however both the Armbian DVFS table and the official one
have operating points with voltage under 1.1V, and both
DVFS table are known to work properly at the lowest
operating point.
Use 1.0V as the minimum voltage instead."
I have tested this on patch two Orange Pi Plus boards, by running a
kernel with this patch and do intermettent runs of cpuburn while
monitoring voltage, frequency and temperature. The board runs stable
across its operatiing points while showing a reasonable (< 40C)
temperature. My Orange Pi PC, when put to the same test, yields similar
stable results.

This patch fixes the warning "xxx has a unit name, but no reg property"
by removing "@0" from such node. 6 board files are fixed. Each has the
same aforementioned issue in pinmux nodes. These include the Nano Pi
family base dtsi file, the Orange Pi 2, Orange Pi Lite, Orange Pi One,
Orange Pi PC, and Orange Pi Plus.

This is also meant to help users realize that it is not valid for

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.

Fix the following issues with the gpio_keys node:
1) Use of undocumented input-name property
2) Use of a unit-address on the sw2 node
3) Having "PL03" in the pinctrl node which does not exist, this should
be "PL3"
And add support for the sw2 button on the board.

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.
