drm/amd/display: fix input states translation error for dcn35 & dcn351

[Why]
Currently there is an error while translating input clock sates into
output clock states. The highest fclk setting from output sates is
being dropped because of this error.

[How]
For dcn35 and dcn351, make output_states equal to input states.
