drm/amd/display: Set the power_down_on_boot function pointer to null
[WHY]
Blackscreen hang @ PC EF000025 when trying to wake up from S0i3. DCN
gets powered off due to dc_power_down_on_boot() being called after
timeout.
[HOW]
Setting the power_down_on_boot function pointer to null since we don't
expect the function to be called for APU.
