Benjamin Cabé 3e7672a71b modules: hal_silabs: Stub countermeasure mask load for no-blob builds
soc_crypto.c now seeds the AES countermeasures through libsxsymcrypt.a,
so add stubs for sx_cm_load_mask() and sx_channel_wait() to fix
CONFIG_BUILD_ONLY_NO_BLOBS builds on Series 3.

The Zephyr Project is a scalable real-time operating system (RTOS) supporting
multiple hardware architectures, optimized for resource constrained devices,
and built with security in mind.

The Zephyr OS is based on a small-footprint kernel designed for use on
resource-constrained systems: from simple embedded environmental sensors and
LED wearables to sophisticated smart watches and IoT wireless gateways.

The Zephyr kernel supports multiple architectures, including ARM (Cortex-A,
Cortex-R, Cortex-M), Intel x86, ARC, Tensilica Xtensa, and RISC-V,
SPARC, MIPS, and a large number of `supported boards`_.
