[RFC PATCH v10 0/7] PCI: rockchip: Move PCIe WAKE# handling into pci core

Currently we are handling wake irq in mrvl wifi driver. Move it into
pci core.

Tested on my chromebook bob(with cros 4.4 kernel and mrvl wifi).


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.
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.

Changes in v8:
Add optional "pci", and rewrite commit message.
Rewrite the commit message.
Add pci-of.c and use platform_pm_ops to handle the PCIe WAKE# signal.

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
Use "wakeup" instead of "wake"
Rebase.

Changes in v3:
Fix error handling.

Changes in v2:
Use dev_pm_set_dedicated_wake_irq.
