The "vpu_0" or "vpu_1" clock trees should not be updated while the clock is running. Enforce this by setting CLK_SET_RATE_GATE on the "vpu_0" and "vpu_1" gates. This makes the CCF switch to the "vpu_1" tree when "vpu_0" is currently active and vice versa, which is exactly what the vendor driver does when updating the frequency of the VPU clock.
