accel/ivpu: Do not trigger extra VPU reset if the VPU is idle
Turning off the PLL and entering D0i3 will reset the VPU so an explicit IP reset is redundant. But if the VPU is active, it may interfere with PLL disabling and to avoid that, we have to issue an additional IP reset to silence the VPU before turning off the PLL.
