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.

/**

 * 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.
