drm/amd/display: adjust visual confirm dpp height offset to be 1/240 of v addressable

[why]
For timing with large v addressable visual confirm is just too small. It is difficult
to tell visually which DPP we are using. On the other hand with timing with small
v addressable visual confirm is too large and covers the UI area.

[how]
We calculate visual confirm dpp height offset based on v addressable so it stays
relatively the same height i.e. 1/240 verticle portion of the screen.
