drm/amd/display: Fix missing parameter details in amdgpu_dm_ism

Update comments in dm_ism_get_idle_allow_delay() and
dm_ism_insert_record() to better reflect their behavior and inputs.

dm_ism_get_idle_allow_delay() computes the delay before allowing
idle optimizations based on history and stream timing.

dm_ism_insert_record() stores idle duration records in the
circular history buffer.

These functions explain what they do, but they do not explain what their
inputs mean.

Fixes the below with gcc W=1:
../display/amdgpu_dm/amdgpu_dm_ism.c:44 function parameter 'current_state' not described in 'dm_ism_next_state'
../display/amdgpu_dm/amdgpu_dm_ism.c:44 function parameter 'event' not described in 'dm_ism_next_state'
