drm/amd/display: Test self refresh entry

Browse source

[Why]
Add KUnit tests for amdgpu_dm_enable_self_refresh(), covering the full
update and unsupported link blocks, the skip count gating, the damage
settle window, and a Replay capable link.

[How]
The power module stays NULL, which every mod_power entry point treats as
a no-op, so the event updates can be reached without a live power
module.
