ptdev: refine the functions name & code position
refine some functions name and put functions under proper sequence - get_remapping_entry -> get_entry - ptdev_native_owned_intx -> ptdev_hv_owned_intx - ptdev_build_native_msi -> ptdev_build_physical_msi - ptdev_build_native_rte -> ptdev_build_physical_rte - update_active_native_ioapic -> activate_physical_ioapic - ptdev_vm_deinit -> ptdev_release_all_entries Signed-off-by: Jason Chen CJ <jason.cj.chen@intel.com>
