Just a couple of minor fixes in preparation for PCIe shutdown (and by
extension CX, AOSD and DDR power collapse - anybody here a fan of
suspend?).

If you want to test this on your machine, you're gonna need:

- https://lore.kernel.org/all/20231227-topic-pmdomain_sync_cleanup-v1-1-5f36769d538b@linaro.org/
- https://lore.kernel.org/all/20231227-topic-psci_fw_sus-v1-0-6910add70bf3@linaro.org/
- https://lore.kernel.org/all/20231227-topic-8280_pcie-v1-0-095491baf9e4@linaro.org/
- All PCIe devices that require fw must be fully booted (so that they can be suspended)
- You must not have any dangling resource votes (not the case on 8280-crd)
