drm/amd/display: rename acquire_idle_pipe_for_layer to acquire_free_pipe_as_sec_dpp_pipe

[why]
Secondary DPP pipes are used for rendering secondary layers of planes.
The name "for layer" doesn't make it obvious. The function is acquiring
a free pipe as secondary dpp pipe only. We rename it so it is more obvious.
In a future follow up change, we want to add functions to acquire free pipe as
opp head pipe or otg master pipe as well. They will have their separate
allocation priority.
