Indeed, it's only the vgpu drm device that was moved to use the pci
parent device. On x86 the vdev always has dma-ops, also
virtio_has_dma_quirk=true for modern Qemu. So I didn't test this code
path and apparently it's only testable on Xen, which is good to know.

Use devm_register_sys_off_handler() that replaces global
pm_power_off_prepare variable and allows to register multiple
power-off handlers.

Kernel now supports chained power-off handlers. Use do_kernel_power_off()

pm_power_off() for now, which will be removed once all drivers will

drivers want, and thus, they could be easily converted to the new API.
Users of the new API should explicitly enable power-off chaining by
setting corresponding flag of the power_handler structure.
