drm/amd/display: Clear the CUR_ENABLE register on DCN314 w/out DPP PG
[Why&How]
ON DCN314, clearing DPP SW structure without power gating it can cause a
double cursor in full screen with non-native scaling.
A W/A that clears CURSOR0_CONTROL cursor_enable flag if
dcn10_plane_atomic_power_down is called and DPP power gating is disabled.
