arm64: dts: qcom: Add support for QCS615 Talos EVK platform

Hi all,

This patch series adds initial device tree and binding support for the QCS615-based Talos EVK SMARC platform.

The Talos EVK is based on the QCS615 SoC and follows the SMARC standard, consisting of a SoM and a carrier board. The SoM integrates the SoC, PMIC, and GPIO interfaces, while the carrier board provides peripherals such as UART, USB, and CAN for evaluation and development.

### Changes in v3:
- Addressed comments from Dmitry regarding USB1 dr_mode and added a DTS comment.
- No functional change in bindings file.

### Changes in v2:
- Renamed compatible to "qcom,talos-evk" (suggested by Dmitry/Bjorn)
- Merged enum entry with existing qcs615-ride block (suggested by Krzysztof)
- Fixed subject and commit message to use imperative mood.
