Extra HAL files for Silicon Labs SDK for Zephyr

This module provides additional HAL content that is not part of upstream Zephyr for use with the Silicon Labs SDK for Zephyr.

The following SDKs are imported:

• simplicity_sdk - Simplicity SDK for EFM32 and EFR32 Series 2 devices

Simplicity SDK

Scripts from hal_silabs are used to update this repository. The file list from this repository is passed to the script as an argument. Assuming a default Zephyr workspace layout where hal_silabs is checked out to a sibling directory, run:

../silabs/scripts/update_simplicity_sdk.py              \
        --src <path/to/simplicity_sdk>                  \
        --dst simplicity_sdk/                           \
        --file-list scripts/simplicity_sdk_files.yaml   \
        --signoff

where <path/to/simplicity_sdk> points to a checked out copy of the Simplicity SDK git repository.

See the README in hal_silabs for more details about commit naming requirements etc.
