drm/amd/display: fix array index out of bound error in DCN32 DML 

commit aeffc8fb21 upstream.

[Why&How]
LinkCapacitySupport array is indexed with the number of voltage states and
not the number of max DPPs. Fix the error by changing the array
declaration to use the correct (larger) array size of total number of
voltage states.
