drm/amd/display: Set exit_optimized_pwr_state for DCN31
[Why] SMU now respects the PHY refclk disable request from driver. This causes a hang during hotplug when PHY refclk was disabled because it's not being re-enabled and the transmitter control starts on dc_link_detect. [How] We normally would re-enable the clk with exit_optimized_pwr_state but this is only set on DCN21 and DCN301. Set it for dcn31 as well. This fixes DMCUB timeouts in the PHY.
