Add initial device tree for the Xiaomi Poco M3 (codename citrus),Hi,
based on the Qualcomm Snapdragon 662 (SM6115) SoC.
Currently working:
- UFS and microSD
- USB host (OTG)
- WiFi
- Bluetooth
- Remoteprocs (ADSP, CDSP and modem)
WiFi, Bluetooth and the remoteprocs 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 GPU display pipeline will
be added later, so the display is currently only available through
simple-framebuffer.

Poco M3 (citrus) is same HW like Redmi 9T (lime) and Remi 9T NFC (lemon) basically is
a lime with NFC.
So i think it would be better make a common base from lemon's devicetree instead of making the same
devicetree again for the different variants where only the compatible and the model property will be
the difference.
Check sm6125-xiaomi-gingkgo-common for example, it was the same case for Redmi Note 8 (ginkgo) and 8T (willow).
