drm/amd/display: Program CURSOR_DST_X_OFFSET in viewport space
[WHAT & HOW]
According to register specifications, the CURSOR_DST_X_OFFSET
is relative to the start of the data viewport, not RECOUT space.
In this case we must transform the cursor coordinates passed to
hubp401_cursor_set_position into viewport space to program this
register. This fixes an underflow issue that occurs in scaled
mode with low refresh rate.
