Some of the efuse-related tests could be ported to pytest-embedded-qemu. For this, we need a few things:

• Generate an eFuse binary before launching QEMU (example)
• Pass the path of eFuse binary to QEMU
• Add a DUT method to set specific eFuses. The simplest option might be to allow calling espefuse.py, connecting it to QEMU over TCP.
• Add a DUT method to clear eFuses between tests.
