PCI: PM: Drop struct pci_platform_pm_ops
After previous changes there are no more users of struct pci_platform_pm_ops in the tree, so drop it along with all of the remaining related code. No functional impact. Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com> Tested-by: Ferry Toth <fntoth@gmail.com>

- * struct pci_platform_pm_ops - Firmware PM callbacks
- *
- * @bridge_d3: Does the bridge allow entering into D3
- *
- * @is_manageable: returns 'true' if given device is power manageable by the
- * platform firmware
- *
- * @set_state: invokes the platform firmware to set the device's power state
- *
- * @get_state: queries the platform firmware for a device's current power state
- *
- * @refresh_state: asks the platform to refresh the device's power state data
- *
- * @choose_state: returns PCI power state of given device preferred by the
- * platform; to be used during system-wide transitions from a
- * sleeping state to the working state and vice versa
- *
- * @set_wakeup: enables/disables wakeup capability for the device
- *
- * @need_resume: returns 'true' if the given device (which is currently
- * suspended) needs to be resumed to be configured for system
- * wakeup.
- *
- * If given platform is generally capable of power managing PCI devices, all of
- * these callbacks are mandatory.
