right, i forgot a 'make config'... now scmi0/qccpucp0 attaches:

scmi0 at mainbus0
qccpucp0 at simplebus0
scmi0: SCMI 2.0

and i have sensors:

hw.sensors.scmi0.power0=0.21 W
hw.sensors.scmi0.power1=0.30 W
hw.sensors.scmi0.power2=0.31 W
hw.sensors.scmi0.frequency0=2976000000.00 Hz
hw.sensors.scmi0.frequency1=3417600000.00 Hz
hw.sensors.scmi0.frequency2=3417600000.00 Hz
