[PATCH v3 3/3] arm64: dts: qcom: talos: Add Talos Lyra EVK board

[Ruchira Revdekar]

From: Avaneesh Kumar Dwivedi <avaneesh.dwivedi@xxxxxxxxxxxxxxxx>

Add the device tree for the Talos Lyra EVK platform which combines
the Talos Lyra EVK SoM and Lyra carrier board.

This device tree adds board-specific peripheral configuration on top
of the SoM, including:

- Native DisplayPort output
- GPIO expanders on i2c5
- SPI-attached TPM (ST33)
- USB host and peripheral controllers
- Power and reset keys

Also adds a talos-lyra-evk-el2 composite DTB combining
talos-lyra-evk.dtb with the talos-el2 overlay for hypervisor-enabled
configurations.
