[ Upstream commit 0c7f7a5150023f3c6f0b27c4d4940ce3dfaf62cc ]
The cooling device properties, like "#cooling-cells" and
"dynamic-power-coefficient", should either be present for all the CPUs
of a cluster or none. If these are present only for a subset of CPUs of
a cluster then things will start falling apart as soon as the CPUs are
brought online in a different order. For example, this will happen
because the operating system looks for such properties in the CPU node
it is trying to bring up, so that it can register a cooling device.
Add such missing properties.

commit c0b0d540db1a8bfb041166c4991dd6f624e8de45 upstream.
Below two wrong nodes in existing DTS files would cause a fail boot since
in fact the address 0 is not the correct place the memory device locates
at.
memory {
device_type = "memory";
reg = <0x0 0x0 0x0 0x0>;
};
memory@80000000 {
reg = <0x0 0x80000000 0x0 0x40000000>;
};
In order to avoid having a memory node starting at address 0, we can't
include file skeleton64.dtsi and instead need to explicitly manually
define a few of properties the DTS relies on such as #address-cells
and #size-cells in root node and device_type in the node memory@80000000.

Add support for the Bananapi R2 (BPI-R2) development board from
BIPAI KEJI. Detailed hardware information for BPI-R2 which could be
found on http://www.banana-pi.org/r2.html
The patch added nodes into the SoC-level file mt7623.dtsi such as CPU OPP
table and thermal zone treating CPU as one of cooling devices and also
added nodes into board-level file mt7623n-bananapi-bpi-r2.dts such as
MediaTek GMAC, MT7530 Switch, the crypto engine, USB, IR, I2S, I2C, UART,
SPI, PWM, GPIO keys, GPIO LEDs and PMIC LEDs. As to the other missing
hardware and peripherals, they would be added and integrated continuously.

MediaTek produces various PMICs. Which one is used depends on the actual
circuit design. Instead of adding the correct PMIC node to every dts file
we instead add a new intermediate dtsi file which adds the PMIC node. For
those boards with the same PMIC, the intermediate mt6323.dtsi could be
reused to save more redundant nodes created on each board device-tree
files.

Since everybody copied my own mistake from the DT binding example,
let's address all the offenders in one swift go.
Most of them got the CPU interface size wrong (4kB, while it should
be 8kB), except for both keystone platforms which got the control
interface wrong (4kB instead of 8kB).
In a few cases where I knew for sure what implementation was used,
I've added the "arm,gic-400" compatible string. I'm 99% sure that
this is what everyone is using, but short of having the TRM for
all the other SoCs, I've left them alone.
