drm/amd/display: Test amdgpu_dm_dcn10_register_irq_handlers

Browse source

[WHAT]
Add KUnit tests for amdgpu_dm_dcn10_register_irq_handlers() covering the
add_id() rejections for the VUPDATE and HPD sources and the
invalid-source guard in the VUPDATE_NO_LOCK loop, and for
amdgpu_dm_register_outbox_irq_handlers() rejecting a source with no
funcs table.

[HOW]
Reuse the shared registration fixture and the fake IRQ service that maps
no source IDs.
