The core drm code calls drm_irq_uninstall() when needed at lastclose.

Due to the fact that most of the drivers didn't keep their mmio regions
mapped from attach, all irq-using drm drivers have a hook in lastclose()
to remove the irq before it unmaps its registers. Since now they all
keep them mapped, this isn't an issue. Remove the redundant calls.
