drm/amd/display: Test power module init

[WHAT]
Add KUnit tests for amdgpu_dm_init_power_module(), covering the skip
when no eDP is detected and the backlight parameter setup loop followed
by the allocation failure report.

[HOW]
mod_power_create() rejects a NULL DC, which walks the full parameter
setup loop without needing a live display core.
