drm/amd/display: update dpp/disp clock from smu clock table

[Why]
The reason some high-resolution monitors fail to display properly
is that this platform does not support sufficiently high DPP and
DISP clock frequencies

[How]
Update DISP and DPP clocks from the smu clock table then DML can
filter these mode if not support.
