Add dts for Ariaboard Photonicat RK3568.
Partially based on downstream board dts. [1]
Working IO:
Debug UART
SDIO QCA9377 WiFi and Bluetooth
M.2 E-Key PCIe WiFi and Bluetooth
M.2 B-Key USB Modem WWAN
Ethernet WAN Port
MicroSD Card slot
eMMC
HDMI Output
Mali GPU
USB Type-A
Not working IO:
Ethernet LAN Port (Lack of SGMII support)
Power management MCU on UART4 (Driver pending)
Not working IO in MCU:
Battery voltage sensor
Board temperature sensor
Hardware Power-off
Hardware Watchdog
Network status LED
Real-time clock
USB Charger voltage sensor
About onboard power management MCU:
A heartbeat must be sent to the MCU within 60 seconds,
otherwise the MCU will restart the system.
When powering off, a shutdown command needs to be sent to the MCU.
When the power button is long pressed, the MCU will send a shutdown
command to the system. If system does not shutdown within 60 seconds,
the power will be turned off directly.
MCU only provides voltage for charger and battery.
Manufacturer removed RK8xx PMIC.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
