Rafael J. Wysocki 9a6058312e PCI/PM: Power up all devices during runtime resume 
Currently, endpoint devices may not be powered up entirely during runtime
resume that follows a D3hot -> D0 transition of the parent bridge.

Namely, even if the power state of an endpoint device, as indicated by its
PCI_PM_CTRL register, is D0 after powering up its parent bridge, it may be
still necessary to bring its ACPI companion into D0 and that should be done
before accessing it.  However, the current code assumes that reading the
PCI_PM_CTRL register is sufficient to establish the endpoint device's power
state, which may lead to problems.

Address that by forcing a power-up of all PCI devices, including the
platform firmware part of it, during runtime resume.
