arm64: dts: qcom: Add Fxtec Pro1X (QX1050) DTS

The F(x)tec Pro1X is a mobile phone released by FX Technologies Ltd
in 2022.

The phone is exactly the same as the Pro1 released in 2019 with some
changes:
- MSM8998 -> SM6115
- Camera button is no longer multistate
- Only one 48MP back camera
- A new keyboard layout picked by the community.

This commit has the following features working:
- Display (using simplefb)
- UFS
- Power and volume buttons
- Pinctrl
- RPM Regulators
- USB (Device Mode)
