Hi,

a small series with a round of SCMI fixes, mostly trivial.

Notably, though:

- patch 4/5 adds a missing binding definition for SCMI SystemPower
  protocol (merged a while ago and probably lost in translation txt->yaml) 

- patch 5/5 addresses a possible deadlock, spotted by LOCKDEP, at SCMI
  stack unload time, when using a virtio transport backend.

Applies on v6.1

Thanks,
Cristian
