Move it into pci core. Tested on my chromebook bob(with cros 4.4 kernel and mrvl wifi). Changes in v11: Only add irq definitions for PCI devices and rewrite the commit message. Address Brian's comments. Only support 1-per-device PCIe WAKE# pin as suggested. Move to pcie port as Brian suggested. Changes in v10: Use device_set_wakeup_capable() instead of device_set_wakeup_enable(), since dedicated wakeirq will be lost in device_set_wakeup_enable(false). Changes in v9: Add section for PCI devices and rewrite the commit message. Fix check error in .cleanup(). Move dedicated wakeirq setup to setup() callback and use device_set_wakeup_enable() to enable/disable. Rewrite the commit message. Changes in v8: Add optional "pci", and rewrite commit message. Add pci-of.c and use platform_pm_ops to handle the PCIe WAKE# signal. Rewrite the commit message. Changes in v7: Move PCIE_WAKE handling into pci core. Changes in v6: Fix device_init_wake error handling, and add some comments. Changes in v5: Move to pci.txt Rebase. Use "wakeup" instead of "wake" Changes in v3: Fix error handling. Changes in v2: Use dev_pm_set_dedicated_wake_irq.
