Since commit 4984979b9b90 ("drm/irq: simplify irq checks in drm_wait_vblank"), the drm driver feature flag DRIVER_HAVE_IRQ is only required for drivers that have an IRQ handler managed by the DRM core. Some drivers, armada, etnaviv, kirin and sti, set this flag without .irq_handler setup in drm_driver. These drivers manage IRQ handler by themselves and the flag DRIVER_HAVE_IRQ makes no sense there.
Drop the flag for these drivers to avoid confusion.

Applied to drm-misc, thanks. -Daniel
Changes for v2:
- Improve commit log per Russell's suggestion
- Add Russell's ACK tag
