[RFC] linux/pci: move pci_platform_pm_ops to linux/pci.h

[Dongsheng Wang <dongsheng.wang@freescale.com>]

From: Wang Dongsheng <dongsheng.wang@freescale.com>

make Freescale platform use pci_platform_pm_ops struct.

If device's not set power state, we will use this interface to put the
device's into the correct state.
