Introduce support for the HONOR MagicBook Art 14 laptop.
This version is based on the initial work by Kirill A. Korinsky [1]
and Valentin Manea [2].

I'm using it with an external display connected to the HDMI port as
a daily driver for quite some time now.

eDP support is broken (screen is eigher grey or grey with noise), thus,
keeping it disabled for now.

Supported:

- Sound (with alsa-ucm-conf config [5])
  - Speakers
  - Headphone jack
- Bluetooth
- Battery
- HDMI
- DP over USB-C
- Touchpad
- Keyboard (with backlight)
- Touchscreen
- WiFi
- USB-C ports
- USB-A port
- UFS
- H/W accel

Untested:

- Camera
- Fingerprint reader
- Sleep/Suspend

Broken:

- eDP

ACPI dumps are available in aarch64-laptops repo [3].
HWids in dtbloader repo [4].

Changes in v2:
- Disabled eDP;
- Dropped displayport dai links (they weren't tested);
- Dropped SBU MUXes as they make DP over USB-C unreliable;
- Link to v1: https://lore.kernel.org/linux-arm-msm/20260501155612.5490-1-mail@etehtsea.me
