PCI/PM: Print config space of devices before suspend
When resuming from hibernation (S4, also known as "suspend to disk") on a
VM, we have seen invalid config space, e.g.,
serial 0000:00:16.3: restoring config space at offset 0x14 (was 0x9104e000, writing 0xffffffff)
To help debug problems like this, log the config space being saved before
suspend, similar to the log in pci_restore_config_dword() when resuming.
