RX6700XT - minimum power limit not detected correctly

After switching to kernel 6.7, I run into this assertion when trying to set the power limit on my rx6700xt to 130W, as I normally do.

amdgpu 0000:03:00.0: amdgpu: New power limit (130) is out of range [182,194] on drivers/gpu/drm/amd/pm/swsmu/amdgpu_smu.c:2549

min_power_limit (182W) here is not being detected correctly -- 130W is not too low a power target (clocks only drop by 150MHz).
