drm/amd/display: Add KUnit tests for crtc set_vupdate_irq

Browse source

Add dm_test_crtc_set_vupdate_irq_dc_busy and
dm_test_crtc_set_vupdate_irq_enable to cover the previously untested
paths in amdgpu_dm_crtc_set_vupdate_irq() where an OTG instance is
assigned: dc_interrupt_set() failing (returns -EBUSY) and succeeding
via a mock IRQ service (returns 0 for enable and disable).
