drm/vc4: Fix warning about vblank interrupts before DRM core is ready.

The SMICS interrupt fires continuously, but since it's 1/100 the rate
of the USB interrupts, we don't really need a way to turn it off.  We
do need to make sure that we don't tell DRM about it until DRM has
asked for the interrupt at least once, because otherwise it will throw
a warning at boot time.
