[PATCH v3 3/3] arm64: dts: qcom: Add Xiaomi Poco M3

[Amir Hanip <killdeath104@gmail.com>]

Add initial device tree for the Xiaomi Poco M3 (codename citrus),
based on the Qualcomm Snapdragon 662 (SM6115) SoC. It shares most of
its hardware with the Redmi 9T, so it includes the common dtsi.

Currently working:
- UFS and microSD
- USB host (OTG)
- WiFi
- Bluetooth
- Remoteprocs (ADSP, CDSP and modem)

WiFi, Bluetooth, the remoteprocs and the GPU zap shader need
device-specific firmware, which is not part of this series. WiFi
additionally needs qrtr, tqftpserv and rmtfs running in userspace,
and the Bluetooth controller needs its BD address set from userspace.

Display panel, touchscreen and the display pipeline will be added
later, so the display is currently only available through
simple-framebuffer. The GPU and its zap shader are enabled, but no
DRM device is registered until the display pipeline is added, so the
GPU is not usable with this series alone.
