Pinebook has an RTL8723CS WiFi + BT chip. BT is connected to UART1
and uses PL5 as device wake GPIO and PL6 as host wake GPIO.
Enable it in the device tree.

A new 'chassis-type' root node property has recently been approved for
the device-tree specification, in order to provide a simple way for
userspace to detect the device form factor and adjust their behavior
accordingly.
This patch fills in this property for end-user devices (such as laptops,
smartphones and tablets) based on Allwinner ARM64 processors.

The binding of R_INTC was updated to allow specifying interrupts other
than the external NMI, since routing those interrupts through the R_INTC
driver allows using them for wakeup.
Update the device trees to use the new binding.

In contrast to the H6 (and later) manuals, the A64 datasheet does not
specify any limitations in the maximum possible frequency for eMMC
controllers.
However experimentation has found that a 150 MHz limit similar to other
SoCs and also the MMC0 and MMC1 controllers on the A64 seems to exist
for the MMC2 controller.
Limit the frequency for the MMC2 controller to 150 MHz in the SoC .dtsi.
The Pinebook seems to be the an odd exception, since it apparently seems
to work with 200 MHz as well, so overwrite this in its board .dts file.
Tested on a Pine64-LTS: 200 MHz HS-200 fails, 150 MHz HS-200 works.

In recent Allwinner SoCs the first USB host controller (HCI0) shares
the first PHY with the MUSB controller. Probably to make this sharing
work, we were avoiding to declare this in the DT. This has two
shortcomings:
- U-Boot (which uses the same .dts) cannot use this port in host mode
without a PHY linked, so we were loosing one USB port there.
- It requires the MUSB driver to be enabled and loaded, although we
don't actually use it.
To avoid those issues, let's add this PHY link to the A64 .dtsi file.
After all PHY port 0 *is* connected to HCI0, so we should describe
it as this. Remove the part from the Pinebook DTS which already had
this property.
This makes it work in U-Boot, also improves compatiblity when no MUSB
driver is loaded (for instance in distribution installers).

The Pinebook does not use the CSI bus on the A64. In fact it does not
use GPIO port E for anything at all. Thus the following regulators are
not used and do not need voltages set:
- ALDO1: Connected to VCC-PE only
- DLDO3: Not connected
- ELDO3: Not connected

The output from the backlight regulator is labeled as "VBKLT" in the
schematic. Using the equation and resistor values from the schematic,
the output is approximately 18V, not 3.3V. Since the regulator in use
(SS6640STR) is a boost regulator powered by PS (battery or AC input),
which are both >3.3V, the output could not be 3.3V anyway.

Allwinner A64 SoC has separate supplies for PC, PD, PE, PG and PL.
VCC-PC and VCC-PG are supplied by ELDO1 at 1.8v.
VCC-PD is supplied by DCDC1 (VCC-IO) at 3.3v.
VCC-PE is supplied by ALDO1, and is unused.
VCC-PL creates a circular dependency, so it is omitted for now.

The pinmux name and label for a specific function should denote which
pingroup it is on, or if there is only one option for the function, have
not enumerating prefix/suffix at all.
The "r_i2c_pins_a" label is renamed to "r_i2c_pl89_pins" to fit our
current style. The node name "i2c" is also changed to "r-i2c-pl89-pins"
to match. The reason for the peculiar name is that the other option for
muxing R_I2C is on the PL0/PL1 pins, so the name has to mention the pin
numbers in addition to the pingroup.

The eMMC 5.0 standard introduced the data strobe (DS) pin. This pin is
not used for pre-5.0 data modes, nor is it found on pre-5.0 eMMC chips.
On the A64, this pin is muxed with spi0's MISO pin. If the DS pin is
included in the mmc2 pinmux by default, this wil prevent the usage
of both mmc2 and spi0 together.
Instead, split out the DS pin to a separate pinmux that only gets used
by boards that actually have it wired up. Currently supported ones
include the Bananapi M64 and Pine64 Pinebook. These are fixed up.

controller, the other is under a internal hub connected to the host-only
controller.)
- USB HID keyboard and touchpad connected to the internal hub.
- USB UVC camera connected to the internal hub.
Power-related:
- A DC IN jack connected to AXP803's DCIN pin.
- A Li-Polymer battery connected to AXP803's battery pins.
Storage:
- An eMMC by Foresee on the main board (in the product revision of the
main board it's designed to be switchable).
- An external MicroSD card slot.
Display:
- An eDP LCD panel (1366x768) connected via an ANX6345 RGB-eDP bridge.
- A mini HDMI port.
Misc:
- A Hall sensor designed to detect the status of lid, connected to GPIO PL12.
- A headphone jack connected to the SoC's internal codec.
- A debug UART port muxed with headphone jack.
This commit adds basical support for it.
