USB: xHCI: PCI power management implementation



This patch implements the PCI suspend/resume.

Please refer to xHCI spec for doing the suspend/resume operation.

For S3, CSS/SRS in USBCMD is used to save/restore the internal state.
However, an error maybe occurs while restoring the internal state.
In this case, it means that HC internal state is wrong and HC will be
re-initialized.
