pci: split shpc_cleanup and shpc_free
object_unparent should not be called until the parent device is going to be destroyed. Only remove the capability and do memory_region_del_subregion at unrealize time. Freeing the data structures is left in shpc_free, to be called from the instance_finalize callback. Acked-by: Michael S.
