For virtual display feature, by hardcoding 0 for the vblank counter and
-EINVAL for the scanout position return value, we signal to the core DRM code that there are
no hardware counters we can use for these.

Now we can program a flip during a vertical blank period, if it's the
one targeted by the flip (or a later one). This allows simplifying
amdgpu_flip_work_func considerably.
agd: update dce_virtual.c as well.

For virtual display feature, as there is no dce engine, so no pageflip irq
generated. So directly call pageflip irq funtion when received vysn interrupt.

For virtual display feature, initialize dce_virtual_crtc_irq_funcs,
dce_virtual_pageflip_irq_funcs. As it has no dce engine, so the
pageflip interrupt won't be generated, and the vsync interrupt will
be generated by smu's periodic timer or software timer which will
be implemented later.
