PCI: set device wakeup capable flag if platform support is present
When PCI devices are initialized, we check whether they support PCI PM
caps and set the device can_wakeup flag if so. However, some devices
may have platform provided wakeup events rather than PCI PME signals, so
we need to set can_wakeup in that case too. Doing so should allow
wakeups from many more devices, especially on cost constrained systems.
