arm64: dts: qcom: Add Lenovo ThinkBook 16 G7 QOY device tree

Browse Source 
Device tree for the Lenovo Thinkbook 16 G7 QOY

The Laptop is a Snapdragon X1 / X1 Plus (Purwa) based device [1].

Supported features:

- USB type-c and type-a ports
- Keyboard
- Touchpad (all that are described in the dsdt)
- Touchscreen (described in the dsdt, no known SKUss)
- Display including PWM backlight control
- PCIe devices
- nvme
- SDHC card reader
- ath12k WCN7850 Wifi and Bluetooth
- ADSP and CDSP
- GPIO keys (Lid switch)
- Sound via internal speakers / DMIC / USB / headphone jack
- DP Altmode with 2 lanes (as all of these still do)
- Integrated fingerprint reader (FPC)
- Integrated UVC camera
- X1-45 GPU

Not supported yet:

- HDMI port.
- EC and some fn hotkeys.

Limited support yet:

- SDHC card reader is based on the on-chip sdhc_2 controller, but the driver from
the Snapdragon Dev Kit is only a partial match. It can do normal slow sd cards,
but not UHS-I (SD104) and UHS-II.

This work was done without any schematics or non-public knowledge of the device.
So, it is based on the existing x1e device trees, dsdt analysis, using HWInfo
ARM64, and pure guesswork. It has been confirmed, however, that the device really
has 4 NXP PTN3222 eUSB2 repeaters, one of which doesn't have a reset GPIO (eusb5
@43).
