drm/amd/display: Cursor flicker when entering PSRSU

Browse Source 
[Why]
The DAL driver may transmit the wrong cursor position to PSRSU
DMUB driver when there are multiple planes.

[How]
Currently the driver apply the HW cursor on the top plane. So we
should only transmit the cursor position on the top plane to
PSRSU DMUB driver.
