ARM SCMI updates for v5.12

Addition of optional interrupt to signal completion of the request when
using SMC/HVC transport as on some platforms they can return before the
SCMI request is completed. Apart from that, we just have a minor fix in
scmi_remove which was found recently as we are now experimenting more on
SCMI as module. Finally, we are adding Cristian as official reviewer for
SCMI since he is more involved in active development of new features.
