drm/amd/pp: use mlck_table.count for array loop index limit
v2: use temporaries to trivially reduces object size.
The for-loops process data in the mclk_table but use slck_table.count
as the loop index limit. I believe these are cut-n-paste errors from
the previous almost identical loops as indicated by static analysis.
Fix these.
