v9
* return -EAGAIN if we want to skip a test
* use CONFIG_IS_ENABLED() rather than IS_ENABLED()
v7
* make test assertions more flexible depending on the number of provided
  protocols
v4
* move 'base'-related changes to the prior commit
* add CONFIG_CMD_SCMI to sandbox_defconfig
v3
* change char to u8 in vendor/agent names
v2
* use helper functions, removing direct uses of ops
