[rtl] Update use of prim_count following port changes

Browse source 
The latest version of `prim_count` from OpenTitan introduces a
`commit_i` input. To retain the behaviour of the previous `prim_count`
this should be set to a constant 1.

The `cnt_next_o` output has been renamed to `cnt_after_commit_o`.
