[PATCH] drm: drop DRIVER_HAVE_IRQ flag for some drivers

[Shawn Guo]

The drm driver feature flag DRIVER_HAVE_IRQ is used to indicates whether
the driver has 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.
