drm/amd/display: Increase num voltage states to 40
[Description]
If during driver init stage there are greater than 20
intermediary voltage states while constructing the SOC
BB we could hit issues because we will index outside of the
clock_limits array and start overwriting data. Increase the
total number of states to 40 to avoid this issue.
