drm/amd/display: Correct unit conversion for vstartup

Browse source

[why]
vstartup is calculated to be a large number. it works because
it is within vertical blank, but it reduces region of blank that
can be used for power gating.

[how]
Calculation needs to convert micro seconds to number of
vertical lines.
