drm/amd/display: change dram_clock_latency to 34us for dcn35
[Why & How] Current DRAM setting would cause underflow on customer platform. Modify dram_clock_change_latency_us from 11.72 to 34.0 us as per recommendation from HW team Reviewed-by: Nicholas Kazlauskas <[email protected]> Acked-by: Zaeem Mohamed <[email protected]> Signed-off-by: Paul Hsieh <[email protected]> Tested-by: Daniel Wheeler <[email protected]> Signed-off-by: Alex Deucher <[email protected]>
