drm/amd/display: Support vertical interrupt 0 for all dcn ASIC
[Why]
When CONFIG_DRM_AMD_SECURE_DISPLAY is enabled, it will try
to register vertical interrupt 0 for specific task.
Currently, only dcn10 have defined relevant info for vertical interrupt
0. If we enable CONFIG_DRM_AMD_SECURE_DISPLAY for other dcn ASIC, will
get DC_IRQ_SOURCE_INVALID while calling dc_interrupt_to_irq_source() and
cause pointer errors.
[How]
Add support of vertical interrupt 0 for all dcn ASIC.
