From: Jacek Lawrynowicz <jacek.lawrynowicz@xxxxxxxxxxxxxxx>
commit 901dd2617c9c3554b2449c8844b6338009112fcf upstream.
Restore PCI state after putting the NPU in D0.
Restoring state before powering up the device caused a Qemu crash
if NPU was running in passthrough mode and recovery was performed.
Fixes: 3534eacbf101 ("accel/ivpu: Fix PCI D0 state entry in resume")
