drm/amd/display: Allow pflips from a framebuffer to itself

Browse source

[Why]
IGT expects that pageflips can be triggered with the same
framebuffer before and after the commit

[How]
Expand the definition of pageflip to include any change
with an old framebuffer and a new framebuffer, even if they're
the same
