Subject: [PATCH] mb/system76/gaze16: Add System76 Gazelle 16

https://tech-docs.system76.com/models/gaze16/README.html

The gaze16 comes in 3 variants due to differences in the discrete GPU
and network controller used.

- NVIDIA RTX 3050, using Realtek Ethernet controller
- NVIDIA RTX 3060, using Realtek Ethernet controller
- NVIDIA RTX 3060, using onboard Intel I219-V Ethernet controller

Tested on the 3050 variant.
Tested with TianoCore (UefiPayloadPkg).

Working:

- PS/2 keyboard, touchpad
- Both DIMM slots
- M.2 NVMe SSD
- M.2 SATA SSD
- 2.5" SSD
- All USB ports
- SD card reader
- Webcam
- Ethernet
- WiFi/Bluetooth
- Integrated graphics using Intel GOP driver
- HDMI output
- Internal microphone
- Internal speakers
- Combined headphone + mic 3.5mm audio*
- 3.5mm microphone input*
- S3 suspend/resume
- Booting to Pop!_OS Linux 21.04 and Windows 10 20H2
- Flashing with flashrom

Not working:

- Discrete/Hybrid graphics
- Mini DisplayPort output (requires NVIDIA GPU)
- 3.5mm audio input/output detection on Windows
