USB: automatically enable wakeup for PCI host controllers

Browse Source 
This patch (as1193b) enables wakeup during initialization for all PCI
host controllers, and it removes some code (and comments!) that are no
longer needed now that the PCI core automatically initializes wakeup
settings for all new devices.

The idea is that the bus should initialize wakeup, and the bus glue
or controller driver should enable it.
